Primaries in Alaska, Florida and Wyoming Narrow Fields in High-Stakes Senate, House and Governor Races

Primary elections in Alaska, Florida and Wyoming on Tuesday will winnow crowded fields in several high-profile U.S. Senate, House and gubernatorial contests, shaping the November ballot and testing influential endorsements.

Alaska: A Top-Four Primary With An Unusual Twist

Alaska’s nonpartisan, top-four primary features incumbent Republican Sen. Dan Sullivan, former Democratic Rep. Mary Peltola and more than a dozen other contenders. Uniquely, the ballot also includes another candidate named Dan Sullivan, who entered the race in June and successfully sued to remain on the ballot after the state’s Division of Elections argued the candidacy could confuse voters. That challenger has said the name is his family name and denied any intent to mislead voters.

Also on Alaska’s ballot, GOP Rep. Nick Begich III is seeking re-election to the state’s single U.S. House seat. Tom Begich, a member of the same political family and a former state Senate minority leader, is running as a Democrat for governor.

Florida: First Election Under New GOP Map

Florida voters are casting ballots under congressional maps redrawn earlier this year by the Republican-controlled legislature. Republicans say the new districts could help them pick up as many as four House seats by making several districts more favorable to former President Donald Trump.

The redistricting has placed several Democratic incumbents into districts that would have leaned toward Trump in 2024, including Reps. Darren Soto, Jared Moskowitz, Debbie Wasserman Schultz and Kathy Castor. On the GOP side, Rep. Cory Mills — who has denied multiple controversies surrounding his tenure — faces a primary challenge from former TV anchor Ryan Elijah.

The open seat being vacated by Rep. Byron Donalds, who is running for governor, drew five candidates, among them former Rep. Madison Cawthorn and former Rep. Chris Collins, who left Congress amid legal troubles and was later pardoned. Former President Trump has endorsed Catalina Lauf, who previously ran for Congress in Illinois.

Wyoming: Hageman Runs For Lummis’ Seat

In Wyoming, Republican Rep. Harriet Hageman is vacating her House seat to run for the U.S. Senate after Sen. Cynthia Lummis announced her retirement. Hageman has President Trump’s endorsement; Trump previously backed her during her 2022 primary bid against Rep. Liz Cheney, who co-chaired the House select committee that investigated the Jan. 6, 2021 attack on the U.S. Capitol.

Nine Republicans and two Democrats are competing in the primary to replace Hageman in the House. Meanwhile, four Republicans are vying in the GOP gubernatorial primary to succeed term-limited Gov. Mark Gordon; the Republican primary winner will face Kenneth Casner, who was unopposed for the Democratic nomination, in November.

What’s At Stake

These primaries will narrow crowded fields, test the influence of high-profile endorsements, and could shift the balance of several key House and Senate contests heading into the general election.
