Haley Barbour: 'Somebody Else Might Get In'

Could the battle for the Republican nomination go all the way to the Republican convention in August? Could we see an entirely new candidate getting into the race?

One long-time Republican leader tells ABC News the answer to both questions is yes.

“If the Republican primary voters continue to split up their votes in such a way that nobody is close to having a majority, then there is a chance that somebody else might get in,” former Republican Party chairman Haley Barbour said in an interview with ABC News.

Barbour calls such a scenario unlikely, but not out of the question.

“I think the odds of having a contested convention are not good but the fact that we are where we are and there is actually a possibility, I guess this is why there is so much talk,” he said.
