Republican presidential front-runner Donald Trump admitted this morning he’s nervous heading into tonight’s Iowa caucuses.

“You have to be a little bit nervous but you have to want to win,” Trump said in a phone interview on “Good Morning America.”

“I just hope everybody is going to be able to get out and vote.”

In the latest Des Moines Register-Bloomberg Politics poll, Trump claims a 5 point lead over of Texas Sen. Ted Cruz.

“We have the biggest crowds,” he said. “We have the most enthusiasm; these rallies are like love fests.”

In response to New Jersey Gov. Chris Christie‘s claim that Trump’s campaign will eventually self-implode, Trump disagreed.

“My life has been a life of success; it’s been a life of winning,” Trump said. “For someone to say that, he’s not doing very well, I think.”
