With roughly a year and a half until the 2024 presidential contest, the field of candidates is largely set. Former President Donald Trump and Florida Gov. Ron DeSantis have dominated the early Republican race, but other candidates including former Vice President Mike Pence, former United Nations Ambassador Nikki Haley and U.S. Sen. Tim Scott of South Carolina are looking for an opening in case either falters. President Joe Biden faces a couple of Democratic challengers but is expected to secure his party's nomination.
