Key dates to watch in the 2024 presidential election

The 2024 presidential election is already in full swing, with former President Trump's lead over his GOP rivals setting the stage for a likely rematch against President Biden.

Some Republican candidates will share the spotlight again Wednesday at the second GOP presidential debate in Simi Valley, Calif. — a critical moment as time runs out for the field to gain ground on Trump.

Kicking off the voting season, Iowa Republicans will hold the first-in-the-nation caucus Jan. 15. Democrats will hold their first primary Feb. 3 in South Carolina, a controversial move that bumped Iowa and New Hampshire from their first-in-the-nation perch.

The last primaries will be June 4. The country will decide the next president Nov. 5.

Here’s what’s coming up in the 2024 election.
