Sen. Rick Scott, R-Fla., the Sunshine State’s senior senator, successfully staved off a primary challenge Tuesday night and will be the GOP’s nominee for re-election in November.

Scott, a former health care executive, also previously launched an intraparty bid to succeed Sen. Mitch McConnell, R-Ky., as the Republican leader in the upper chamber.

Scott barely survived a challenge from current NASA administrator Bill Nelson by about one-eighth of a percentage point in his 2018 race.

In 2000, the U.S. Supreme Court’s ruling in Bush v. Gore put an end to the tallying of "hanging chads" on paper ballots as the Sunshine State narrowly went to pick then-Texas Gov. George W. Bush in the presidential election.

These days, the state has reliably re-elected statewide Republicans, including Gov. Ron DeSantis, who trounced former Rep. Charlie Crist, D-Fla., in 2022.
