Primary developments in Florida and Alaska offered a fresh snapshot of the battle for control of Congress, highlighting Republican strength in Florida, divisions within both parties and a potentially competitive Senate contest in Alaska. In Florida, Democratic socialist Angie Nixon upset Alex Vindman in the Democratic Senate primary despite being vastly outraised, a result nonpartisan analysts said likely weakens Democrats' chances against incumbent Republican Senator Ashley Moody in a state where registered Republicans outnumber Democrats by 1.5 million. Republican candidates also drew roughly 1.6 million votes in the statewide Senate and governor contests, compared with 1.2 million for Democrats, while a new congressional map could add four GOP-held House seats. Ahead of the Republican governor primary, Kalshi traders gave U.S. Representative Byron Donalds a 99% implied chance of winning the nomination, compared with 1% for James Fishback and 0.5% for Lt. Gov. Jay Collins; traders forecast Fishback would receive 10.3% of the vote. Donalds had President Donald Trump's endorsement and, with an allied PAC, raised $111 million as of mid-August, according to Decision Desk HQ's Geoffrey Skelley. If elected, Donalds would become Florida's first Black governor. Fishback faced a residency lawsuit from Collins, but a Leon County Circuit Court judge allowed him to remain in the race. Trump's endorsements had mixed results elsewhere, helping Donalds and Sydney Gruters but not Catalina Lauf or Representative Cory Mills. In Alaska, centrist Democrat Mary Peltola led incumbent Republican Senator Dan S. Sullivan in the nonpartisan Senate primary, with 48% to Sullivan's 42.8% with 93% of precincts reporting. Another candidate, Dan J. Sullivan, was third with 2.4%; Republicans said the similar name could confuse voters, and the U.S. Justice Department was investigating, according to a source familiar with the matter.
