President Ocasio-Cortez, Vice President Buttigieg: What Their Records Say About a First 100 Days Built to Undo Trump’s Agenda

01 The Scenario — and Why the Record Makes It Analyzable

This is a scenario, not a forecast. Neither Alexandria Ocasio-Cortez nor Pete Buttigieg has announced a national candidacy, let alone a shared ticket, and the premise here is exactly the one N43 applies to every “first 100 days” piece: analyze what their existing records suggest they would prioritize, so the analysis is falsifiable against those records rather than drifting into partisan fan fiction. Public discussion of a 2028 field is not candidacy.

The pairing is analytically interesting precisely because the two halves are so different on paper. Ocasio-Cortez is a seven-year House legislator with 74 sponsored bills and 1,655 cosponsorships concentrated in housing, labor, environment and civil rights, the author of every Congress’s Green New Deal for Public Housing Act, and co-sponsor of the Medicare for All Act (H.R. 3069). Buttigieg spent 2021–2025 as the 19th Secretary of Transportation — a cabinet department he ran through the largest infrastructure law in half a century, more than $9.5 billion in discretionary grants across 800-plus projects, and the supply-chain crises of the pandemic years. She legislates; he has administered.

The August 2026 Emerson College poll puts the electability gap in numbers. Buttigieg leads the hypothetical Democratic field, beating both Marco Rubio and JD Vance 49–44 in trial heats. Ocasio-Cortez trails both: 43–48 against Rubio and 44–46 against Vance — the only tested Democrat losing to both Republicans. A composite ticket is the kind of idea poll numbers invite and primaries punish. But the question here is not whether it would win; it is what the record says such an administration would actually do — and on that, the record is unusually legible, because most of the first 100 days would be aimed at a specific, enumerable target.

02 Day 1: Executive Orders and the Emergency-Power Reversal

The phrase “come out swinging hard to undo” is not just rhetorical in this case, because the Trump administration’s second-term economic architecture was built disproportionately on instruments a successor can withdraw by executive order. The Liberation Day tariffs rest on Executive Order 14257 (April 2, 2025), which invoked the International Emergency Economic Powers Act to declare a national emergency over the trade deficit. The February 2025 Canada, Mexico and China tariffs rest on Executive Orders 14193, 14194 and 14195 — same statute. A president who revokes the emergency declarations revokes the tariffs, subject to the notice periods in the orders themselves.

The courts have already marked the path. The Court of International Trade struck down the IEEPA tariffs on May 28, 2025, in Trump v. V.O.S. Selections; the en banc Federal Circuit upheld that ruling on August 29, 2025. Whatever the Supreme Court ultimately does, a successor administration would not wait: an Ocasio-Cortez Justice Department would simply stop defending the positions and an Ocasio-Cortez USTR would revoke the emergency declarations. That is a Day-1-to-Day-10 action in a way that, say, reversing the statutory Section 232 steel and aluminum tariffs is not — those rest on Commerce Department determinations with their own procedural clocks.

Day 1 for this pairing, grounded in what each has actually advocated, would likely stack: rejoining the Paris Agreement by the letter-to-the-UN mechanism that takes effect in 30 days; revoking the IEEPA emergency declarations; restoring Schedule F-reversed civil-service protections at the agencies; and reopening the DACA and parole programs wound down since 2025. Buttigieg’s Day 1 file is different in kind — his record suggests he would spend it on personnel: re-staffing the grant-making offices at Transportation that distributed the 2021 law, on the theory that agency capacity, not press releases, is what the first 100 days are actually made of.

03 Days 2–30: Rebuilding the Agencies That Do the Undoing

Days 2 through 30 is where the two records divide the work most cleanly. Ocasio-Cortez’s committee and sponsorship history points at the financial and environmental regulators: the Consumer Financial Protection Bureau, where her credit-card interest cap bill (H.R. 1944, the 10 Percent Credit Card Interest Rate Cap Act) implies an aggressive supervisory posture; the EPA, where her Green New Deal resolutions — H.Res. 109 in 2019, renewed each Congress through H.Res. 332, 319 and their successors — imply restoration of the regulatory authority bill she introduced in a prior Congress (H.R. 8395) to formally reaffirm; and the Labor Department, where her 17% labor-and-employment sponsorship share and the Fair Wages for Home Care Workers Act (H.R. 7917) telegraph wage-rule attention.

Buttigieg’s four years running DOT give the scenario something rare: a vice president who knows exactly where the career staff, grant dockets and rulemaking pipelines are. His department-by-department recall list would be practical rather than ideological — port congestion metrics, bridge-formula apportionments, the discretionary programs that made up the $9.5 billion in awards he oversaw. His own framing of the job was “organizational excellence” across five goals: safety, jobs, equity, climate, innovation. Expect a VP portfolio that looks like a delivery unit.

The undo ledger in this phase is mostly rule-for-rule. Each regulation the current administration suspended or proposed for revocation has a restoration path through notice-and-comment — slower than executive order, faster than statute. An agency-level undo program is where “swinging hard” gets its substance: hundreds of small administrative actions that collectively re-price whole industries, exactly as the first-year Trump administration ran the program in reverse.

04 The Tariff Rollback — What Falls, What Survives, What Gets Replaced

The tariff question deserves its own section because it is the one place where the undo project collides with the ticket’s own politics. Ocasio-Cortez has been a trade-skeptic vote in the House, not a free-trade vote; the progressive left does not read the Liberation Day orders as wrong in direction so much as wrong in design — revenue raised from consumers, no industrial policy attached, allies and adversaries tariffed alike. AOC’s undo of the IEEPA stack would likely be paired with a demand for something in return: procurement standards, domestic-content rules attached to the infrastructure money Buttigieg knows how to move.

What survives any reversal matters as much as what falls. The Section 301 China stack, layered by the second-term orders on top of legacy duties, is statutory — withdrawing it requires affirmative USTR process, not a signature. The October 2025 critical-minerals expansion and the February 2026 semiconductor tariffs (25% on logic and memory above 14nm) run through Section 232 investigations with Commerce findings behind them. A first-100-days fact sheet would distinguish what the pen can reach from what the machinery holds in place — and the honest version concedes the machinery holds most of the China architecture, which is why the China hawks in both parties would quietly approve of that part surviving.

Buttigieg’s addition to the trade file is the supply-chain lens from his cabinet years: the port-congestion playbook he ran in 2021–22, cutting long-dwelling containers in half, is the kind of operational credibility a rapid tariff unwinding needs if importers surge orders ahead of effective dates. His 2026 media posture — “taking on Trump’s failures” on inflation and governance, in his own broadcast appearances — suggests he would frame the rollback as cost-of-living relief, not as a concession.

05 The First Budget: Her Bills, Their Reconciliation Math

The first budget request is the first test of what this pairing actually is, and their records diverge here in a way the campaign trail would never fully expose. Ocasio-Cortez’s legislative signature is large and specific: the Green New Deal for Public Housing Act — reintroduced August 6, 2026 as H.R. 10063 with roughly 40 cosponsors, the fifth consecutive Congress carrying it — which would fund energy retrofits and resident employment programs in public housing nationwide. Medicare for All, of which she is a longtime co-sponsor via Jayapal’s H.R. 3069, is the headline divergence: Buttigieg’s 2020 counter-proposal, “Medicare for All Who Want It,” was designed precisely against that bill. A first budget would have to pick, and reconciliation rules (fiscal effect only, 50-vote threshold, parliamentarian vetting) make the public-housing bill far more survivable than the health bill.

Her smaller-bore bills are the ones with actual crossover precedent: the 10% credit-card cap, the Fair Wages for Home Care Workers Act, the Geothermal Cost-Recovery Authority Act (H.R. 398, which reached the Union Calendar), the Healthy Start reauthorization (H.R. 3302, placed on calendar in 2025). This is the tell in the record: the bills she has pushed that move are the ones a narrowly divided Congress could pass in the first 100 days, and a serious scenario gives them priority over the signature bills that cannot move.

What requires Congress, plainly: Medicare for All needs a generational majority and would not reach a floor vote. Any Green New Deal appropriation above reconciliation limits needs 60 Senate votes. The filibuster question — whether this pairing would back carving it out for legislation — is where the record is genuinely silent, and honesty about that silence is part of keeping the analysis falsifiable.

06 What Buttigieg Brings: Delivery, Supply Chains and the Moderate Half

The vice presidency in this scenario is not a consolation prize; it is the delivery mechanism. Buttigieg’s cabinet file is the largest operational asset either partner brings. Beyond the grant programs, his department produced the national roadway safety strategy, distributed emergency transit relief, and intervened in supply-chain shocks — the exact tool kit an aggressive first-100-days agenda needs when its announcements collide with procurement reality. Before that, two terms as mayor of South Bend (2012–2020), where unemployment was cut in half on his watch, plus seven years as a Navy Reserve officer with a 2014 Afghanistan deployment — a governance resume that reads as the moderating credential against a president from the Democratic Socialist tradition.

That tradition is the political problem the poll quantifies. Emerson’s August numbers show 46% of Democrats describe themselves as supportive of Democratic Socialists — concentrated at 53% among voters under 50 — but only about 20% of independents do, and it is independents who make Ocasio-Cortez the only Democrat losing to both Republicans tested. The pollster’s own read: moderates like Buttigieg, Ossoff and Newsom perform better in a general electorate, and the new South Carolina-first primary calendar for January 2028 favors exactly that moderate lane, the way it shaped the 2020 race.

The internal tension is therefore the story. A Buttigieg vice president would be the administration’s face on the programs he ran (infrastructure, supply chains, safety) and its translator to the voters who chose the ticket despite its top half. An Ocasio-Cortez president would be the mandate on the programs only she has legislated (housing retrofits, care wages, credit caps). The record suggests the working compromise lands on delivery: spend the first 100 days on the undoable and the passable, and let the big bills wait for a Congress that does not yet exist.

07 What Courts, Congress and Falsifiability Do to the Plan

Every first-100-days analysis ends at the same three constraints, and this one is no exception — but the specific texture matters. The courts: the same federal judiciary that struck down the IEEPA tariffs on non-delegation-adjacent grounds would test a progressive administration’s own emergency-power innovations just as fast; a president whose movement has criticized imperial executive power would face the temptation to use it on Day 1, and the litigation would arrive by Day 30.

Congress: the Senate map for this hypothetical session is unknowable from here, but the mechanism is fixed — reconciliation for the budget, 60 votes or a carve-out for the rest. The House record is instructive: Ocasio-Cortez’s bills that reached calendars were bipartisan-coded infrastructure and reauthorizations. That is the actual first-100-days legislative profile: H.R. 398-style geothermal authority and H.R. 3302-style reauthorizations move; H.R. 3069 does not.

What would falsify this analysis: watch for whether either figure distances themselves from the specific pieces cited here — if Ocasio-Cortez drops the public-housing bill from her next Congress, the centerpiece falls; if Buttigieg embraces single-payer, the internal-tension thesis collapses; if either proposes a filibuster carve-out, the legislative pessimism is wrong. The value of the exercise is that their records make it checkable — which is what separates analysis from the fan fiction it explicitly refuses to be.
