The number of candidates in the Republican presidential primary continues to grow. Florida Governor Ron DeSantis officially joined the race as candidates emboldened by his dropping poll numbers launched their own bids earlier.

The addition makes seven Republicans in the primary, where former President Donald Trump continues to be the frontrunner. And a growing cast of contenders is good for Trump, who polls show doing better against a larger field where the anti-Trump vote is splintered into various factions. Indeed, when South Carolina Senator Tim Scott launched his campaign, Trump wished him well.

“Good luck to Senator Tim Scott in entering the Republican Presidential Primary Race,” Trump wrote on his Truth Social account. “It is rapidly loading up with lots of people.”

Still, some potential contenders have bowed out, as former Maryland Governor Larry Hogan, a longtime Trump antagonist, and Mike Pompeo, who was secretary of state under Trump, have announced that they won’t run for president.

Republicans Who Might Challenge Trump
