Bill Clinton Says He's Leaving It 'All on the Floor' in Iowa

The former president was campaigning for his wife.

"You just want to know you left it all on the floor, and I think we did," the former president told ABC News.

"We've had a chance to get her message out. I feel good about it but you don't know what's going to happen," Bill Clinton said, noting Iowa's history of unpredictability when it comes to choosing who wins the state's caucuses.

Following a campaign event at a college in Grinnell, Iowa, today, the former president greeted supporters mentioning his fond memories in Iowa both while he was campaigning for his own presidential bid and also for his wife's eight years ago. ABC News caught up with the president immediately following his speech asking him if Iowa feels any different than it did eight years ago when Hillary Clinton first ran.

"It feels good, I mean you never know what's going to happen here, but it feels good," the former president said. "First of all she's got so many wonderful young people working for her in all these communities. And I think she's done a really good job. She's made a serious commitment to Iowa."

A Hillary Clinton campaign staffer told ABC News this was the youngest crowd they have seen at any of the president's events.

Bill Clinton will continue stumping his way through Iowa and New Hampshire in the coming days, and his team announced today that the president will also shift his efforts to South Carolina next week.
