Polls reveal uncertainty among American voters for 2024 presidential race.

A new poll by Monmouth University shows that American voters are more certain about who they won't support in the 2024 presidential race than who they will. The poll tested hypothetical head-to-head match-ups between Democratic President Biden and Republicans former President Trump, former Vice President Mike Pence, and Florida Gov. Ron DeSantis. The poll found that between 44 and 46 percent of voters said they "definitely" won't back Biden, while roughly one-third of likely voters said they'll definitely vote for Biden against both Trump and DeSantis. The GOP presidential primary field has gotten more crowded in recent weeks with the entries of DeSantis and Sen. Tim Scott (R-S.C.) into the race, joining Trump, former South Carolina Gov. Nikki Haley, former Arkansas Gov. Asa Hutchinson, and entrepreneur Vivek Ramaswamy.
