June 24 Primary Roundup: Centrists Hold in Maryland, a Trump-Backed Challenger Claims NY-19, and Utah Gets a Competitive Fall Race

Tuesday night added four specific outcomes that sharpen the picture heading into fall.

Maryland: Ferguson Survives, Trone Doesn't Come Back

Maryland Senate President Bill Ferguson beat progressive challenger Bobby LaPin 56.6% to 43.4% in Baltimore-centered Senate District 46, according to Fox News. LaPin, an Army veteran and charter boat owner with a sizable social media following, ran explicitly as a Sanders-style insurgent, calling Ferguson "a Chuck Schumer" in his campaign pitches. The margin wasn't close, but 43% for an unknown activist against one of the state's most powerful Democrats is a number Ferguson will remember.

The race had a sharp edge beyond ideology. LaPin targeted Ferguson directly for blocking a congressional redistricting effort backed by Governor Wes Moore and national Democratic leaders. Ferguson reportedly called the proposed map "objectively unconstitutional" and warned that "the legal risks are too high" and "the downside risk to Democrats is catastrophic," according to The Washington Post and WTOP. Moore conspicuously declined to endorse Ferguson despite their shared party and overlapping institutional roles. Ferguson won anyway.

Also in Maryland, incumbent Rep. April McClain Delaney defeated billionaire David Trone in a House primary that became one of the most expensive intraparty races of the 2026 cycle. Combined spending exceeded $32 million, per Fox News, with Trone putting in more than $25 million of his personal fortune and Delaney spending at least $7 million of her own. Trone, founder of Total Wine & More, had previously spent over $60 million on a failed 2024 Senate bid against Angela Alsobrooks.

The policy dispute between them was narrow. Trone hammered Delaney for voting for the Laken Riley Act in early 2025, which mandates detention of undocumented immigrants accused or convicted of certain crimes. Delaney later said she regretted that vote. Trone separately drew criticism for featuring Hillary Clinton in an ad without a formal endorsement from her. Maryland's Democratic establishment, including Moore, Sens. Chris Van Hollen and Angela Alsobrooks, backed Delaney. That institutional weight held.

A fair concern from Trone's supporters: incumbency plus institutional backing in a gerrymandered district creates a nearly insurmountable structural advantage that has little to do with which candidate voters actually prefer on the merits. That argument isn't wrong. It just didn't produce a different result Tuesday.

New York: Trump's Pick Wins NY-19 GOP Primary

In New York's 19th Congressional District, state Sen. Peter Oberacker won the Republican primary Tuesday and will challenge incumbent Rep. Josh Riley, D-N.Y., in November, according to Fox News. Trump endorsed Oberacker earlier this year, calling him a fighter for economic growth, border security, and energy dominance.

Oberacker has served in the New York State Senate since 2021, with a legislative record focused on rural agriculture, ratepayer energy costs, and utility transparency. He has raised just under $1 million through FEC filings. Riley holds the seat now, but Republicans won NY-19 in 2022. The district has genuinely flipped before, which is why both parties are paying attention.

Oberacker's central line of attack is Riley's ties to the utility industry while Riley publicly criticizes energy companies on the campaign trail. Whether that contrast lands with a rural district's voters is the open question between now and November.

Utah: McAdams Gets the Nomination, Now Faces a Real Race

Former Rep. Ben McAdams won the Democratic nomination for Utah's newly created 1st Congressional District, defeating state Sen. Nate Blouin, Michael Farrell, and former tech worker Liban Mohamed in a four-way primary, according to Fox News. Total spending on the Democratic side alone reached approximately $4.6 million, with McAdams raising roughly $1.9 million, more than his three opponents combined.

Blouin had backing from Sen. Bernie Sanders. McAdams ran explicitly as a centrist with a track record of winning in Republican-leaning Utah. McAdams previously held Utah's 4th District from 2019 to 2021 before narrowly losing reelection.

The district itself exists because of litigation. A court struck down the Utah legislature's prior congressional map, ruling it diluted Salt Lake County voting strength by splitting the area across multiple districts. The new 1st District is Salt Lake City-based and leans Democratic by design. McAdams now faces Republican Riley Owen in November in what is expected to be Utah's most competitive congressional race.

The Sanders-backed Blouin camp's argument was straightforward: a safe Democratic-leaning district should elect a genuine progressive, not a Democrat who will spend the next two years triangulating. That's a legitimate strategic disagreement within the party. McAdams's counter is grounded in fact. His history of actually winning in hostile territory makes him the stronger general-election candidate.

The Pattern Across All Four Races

These results reveal a consistent pattern. Centrist and establishment Democrats won when challenged from the left (Ferguson in Baltimore, Delaney over Trone, McAdams over Blouin). Progressive insurgents pulled significant vote share but fell short. On the Republican side, Trump-backed candidates in competitive districts consolidated the nomination without serious opposition.

Whether NY-19 and Utah-1 will actually flip heading into fall remains unresolved. Both districts have genuine swing histories. Oberacker faces an incumbent with name recognition and a fundraising base; McAdams faces a Republican opponent in a state that leans red at the presidential level regardless of how the new district is drawn. Neither race is settled, and neither party has a structural lock on the outcome.
