Our verdict

LiberalMind endorses Joseph Arminio — as unproven in Congress, and on watch

Election Day is Tuesday, November 3, 2026, and voting is already underway in Delaware. This is the whole race — the records, the claims against each candidate, and what the sources actually show. Read the research, and decide which flaw you can live with.

The setup

Delaware has a single House district, at-large, held by Rep. Sarah McBride (D), first elected in 2024 and now seeking a second term. The Cook Political Report puts the district at PVI D+8 and rates it Solid D (Cook Political Report race finder). McBride won the seat with 57.9% in 2024 (Wikipedia, citing Cook's 2024 House Vote Tracker).

On the printed ballot, per the Delaware Department of Elections' official 2026 sample ballots — the strongest source in our research — are exactly two names: Sarah McBride (Democratic) and Joseph "Dr. Joe" Arminio (Republican), plus a write-in line. No minor-party or independent candidate is printed for this office. Two registered write-ins rest on a single compilation (Delaware LIVE News): Earl Cooper, a defeated Republican primary candidate, and Scott Walker, whose write-in filing Delaware LIVE reports was still under state review at its guide's publication. Walker's status is unresolved in the sources, and we print both names as write-ins only, at that strength.

Sarah McBride (Democratic)

McBride is Delaware's sole House member and the first openly transgender member of Congress (Delaware Online). Before the House she represented Delaware's 1st Senate District in the state Senate — dated 2021–2025 in the Ballot Brief's account and 2020–2025 in her House biography, an election-versus-swearing-in difference, not a substantive conflict — where she passed the Healthy Delaware Families Act creating Delaware's paid family and medical leave program. Earlier she worked for Gov. Jack Markell and Attorney General Beau Biden, in the Obama-Biden White House, and as national spokesperson for the Human Rights Campaign (Ballot Brief, citing her official House biography and campaign site). She was unopposed for the Democratic nomination. Her re-election case, as reported by Delaware Online from her office, is that she introduced five bipartisan bills and co-sponsored 439 pieces of legislation in her first term and helped secure more than $164 million in federal funding for Delaware since 2025 — we attribute those figures to her office, as our research directs.

Pros: A state-senate record with a signature enacted law; a first House term her office documents with bipartisan bill introductions and federal funding secured; a 57.9% first win in a D+8 state.

Cons: Bipartisan bill introductions are not the Manchin test. The exception requires proven breaks with her party on our values, in service — and this file shows a Democrat whose career has run through Democratic governors, a Democratic White House, and an advocacy organization of the left, with no such break documented. Co-sponsorship counts are activity, not dissent.

The flaw, plainly: McBride's flaw is the unexceptioned record itself: one term in the House, a career inside her party's institutions before it, and nothing in the verified file that breaks toward our values. Her organizing vote prices at House weight, against her.

Joseph Arminio (Republican)

Arminio, a medical doctor, won the September 15 Republican primary with 47.9% in a three-way race — John J. Whalen 32.2%, Earl Cooper 19.9% (Wikipedia compilation of official results; Delaware Online rounds his share to "nearly 48%"). His campaign-site biography, as summarized by the Ballot Brief, lists positions with the Department of Defense, the American Enterprise Institute, and High Frontier; the chairmanship of the National Coalition for Defense, 1996–2000; teaching history, world politics, American government, and debate at American University and Lincoln University; the founding of the Statesman Debate Institute; and seven books on American policy and history. Wikipedia additionally describes him as a candidate for Maryland's 1st congressional district in 2008. His campaign themes, per Delaware Online, are the economy, national defense, and immigration.

One conduct item is in the file and we print it as documented: Delaware Online reports Arminio was removed from a post-primary candidates forum after repeatedly misgendering McBride, and that Republican Senate nominee Michael Katz called for his withdrawal. Arminio remained the nominee. We price that as reported campaign conduct — voters can weigh it — and it is not, under our doctrine, a disqualifying act or proof of inability to lead.

Pros: A defense-policy career — the Pentagon, a conservative think tank, a defense coalition chairmanship — aimed squarely at the national-defense theme of his campaign; a plurality primary win against two opponents; the conservative direction in Delaware's only House race.

Cons: He has never held elected office, and 47.9% in a three-way primary is a plurality, not a consolidation. The forum removal, as reported, is campaign conduct his own party's Senate nominee answered by calling for his withdrawal — a party-unity cost printed at its sourced strength.

The flaw, plainly: Arminio is unproven in office, with a documented conduct episode on the campaign trail. Unproven earns a watch, not a demerit; the episode is priced as conduct, and neither fact, under our doctrine, outweighs the direction on offer.

OUR CALL

LiberalMind endorses Joseph Arminio — as unproven in Congress, and on watch.

McBride's first term, on the office's own figures, was an active one — and activity inside her party's program is exactly what the exception test measures against. No proven break on our values is in this record, so the exception is not earned, and her organizing vote weighs as an unexceptioned Democrat's weighs in the House: lighter than a senator's, and still against her. Arminio offers the conservative direction out of a defense-policy career, with no office held and therefore nothing proven against him in service. We endorse him unproven and on watch, in a D+8 Solid D state, as a direction call — printed as such.
