Republicans are looking ahead to August, when they officially choose a nominee for President. There's a small chance that when the candidates arrive in Tampa for the Convention, none of them will have enough delegates to clinch the nomination. And if there's a stalemate, then all bets are off.
FOX's Shannon Bream has more from America's Election Headquarters in Washington:
What are the odds Republicans do not have a settled nominee by their August convention? Most call the scenario highly unlikely, while others are increasingly convinced it could happen.
As for the possibility that a new face like Mitch Daniels or Jeb Bush could get into the mix, political analysts say it's not impossible, noting that a late addition could take part in several remaining state contests if the field doesn't gel on Super Tuesday.
