"Iowa Caucus 2024: Live Updates, Results, and Political Survival"

The Iowa caucuses have begun, with Republican candidates like Ron DeSantis and Nikki Haley vying for support. DeSantis celebrated a second-place finish, while biotech entrepreneur Vivek Ramaswamy suspended his campaign and endorsed Donald Trump. DeSantis is projected to finish ahead of Haley but behind Trump. Trump won the caucuses, and his super PAC called on other candidates to drop out. Florida Republicans, including DeSantis' mother, have been active in Iowa, and DeSantis and Haley have been making their final pitches. The caucuses could solidify Trump's frontrunner status, but a strong second-place finish for DeSantis or Haley could establish them as the leading alternative to Trump.
