Noting that Donald Trump had vowed to drop out of the presidential race if his poll numbers collapse, Fox News’ Megyn Kelly asked Bush, “What would it take to make you get out?”

“I’m not getting out. I believe we have a plan to be very competitive in the early states. We have the resources to stay with this,” Bush told Kelly. “I’m campaigning hard, I’m campaigning with heart, I’m campaigning in a way that will draw people towards our cause.”

“This is the beginning of a hard race. I never thought it would be easy and it certainly hasn’t been. … I believe that I’m gonna win the nomination,” he said.
