Republican Ron DeSantis refused to rule out a 2024 presidential run on Monday evening as he seeks a second term as Florida governor, declining to address challenges from Democratic nominee Charlie Crist to promise to serve out a full four years if reelected.

DeSantis instead suggested that he had no interest in challenging President Joe Biden . The only worn-out old donkey Im looking to put out to pasture is Charlie Crist, he said.

The exchange came during the sole debate between Crist and DeSantis in the general election campaign, barely two weeks before Election Day, as Crist attempted to use DeSantis presumed interest in a White House bid and his full support for a new 15-week abortion ban to claw back into a race that appears to be moving in DeSantis direction.

He wont even tell you if hell serve four years if you reelect him. I mean, come on. You deserve better than that, Crist told the audience in the Fort Pierce auditorium and watching on television.
