Democratic socialist scores shock win, and other takeaways from US primaries

Another surprise victory for a left-wing Democratic candidate and a triumph for an incumbent Republican senator over a challenger with the same name were among the notable plotlines as primary elections took place in various parts of the US on Tuesday.

Florida and Alaska were two of the latest states to hold primaries, as Republicans and Democrats narrow down their field of candidates ahead of November's midterm elections. Among other things, the midterms will decide which party controls the US Congress - which in turn will have a bearing on the presidency of Donald Trump. Here's a quick digest of some of the goings-on from the two states on Tuesday night. Former Republican to take on Trump endorsee for Florida governor The Florida governor contest in November now looks set to be fought by two candidates for whom the Trump track record is a key issue in the president's adopted home state. US media outlets have projected victories for Republican Byron Donalds and Democrat David Jolly in their respective party primaries, meaning the pair will face off in the contest in November. Donalds, who is a sitting US congressman, had the endorsement of Trump. "We have won a massive victory," Donalds said before a cheering crowd on Tuesday evening. "Let's go beat David Jolly in November." Jolly is a former Republican congressman who left the party and criticised Trump before changing party. Recent history is not on Jolly's side: Democrats have not held the Florida governor's mansion since 1999. The term of current governor, Ron DeSantis, is expiring. "We are celebrating more than just a primary victory," Jolly told his supporters after most votes had been tallied. "We are celebrating the return of a resiliency, the renewal of a hope."
