"Republicans Haley and DeSantis vie for No. 2 spot in White House race at fourth GOP debate"

Florida Governor Ron DeSantis and former U.S. Ambassador to the U.N. Nikki Haley will face off in the fourth Republican presidential debate, vying for the No.2 spot as an alternative to former President Donald Trump. With Trump leading in the polls, DeSantis and Haley are racing to establish themselves as the preferred choice for voters looking to move beyond Trump. The debate, which also includes Vivek Ramaswamy and Chris Christie, could be the last chance for DeSantis or Haley to make a lasting impact before the Iowa nominating contest. Trump himself will not be participating in the debate.
