Bill Clinton Says Hillary in ‘Dog Fight’ for Iowa Caucus Win

DAVENPORT, Iowa— -- With less than three days until the Iowa Caucuses, Hillary Clinton leaned on a long-kept, family motto -- “we're all in this together” -- on Friday as she linked up with her husband and former President Bill Clinton at a joint campaign rally.

The event, which came after a packed day of television interviews and campaign events across the state, was part of the Clinton campaign’s aggressive, final stretch strategy -– a topic Bill Clinton addressed.

“This is a dog fight. You fight to the last hour,” the former president told ABC News when asked what his wife needed to do over the next three days to see a victory Monday.

Several polls show Hillary Clinton neck-and-neck with her chief rival, Vermont Sen. Bernie Sanders. Voter turnout was expected to be a major factor in determining the caucus winner.

To rally support, both Clintons have been stumping in Iowa over the past few days, holding more than 25 campaign events combined. Their daughter, Chelsea Clinton, was scheduled to join them on the trail this weekend.

“You need to touch as many people as you can,” Bill Clinton explained.

Aides to Clinton –- and the Democratic presidential candidate herself –- see the former president as one of their biggest assets in these final days.

“I brought a pretty good warm-up act, don’t you think?” Hillary Clinton asked the crowd of roughly 1,5000 packed into the Col Ballroom on Friday.

Bill Clinton played down his role in bringing out the crowds, however.

“She’s doing fine well on her own,” he said as took selfies and shook hands on the rope line.

When asked how confident he was about winning Monday, the former president responded with a mix of confidence and caution.

“I feel good,” Clinton said. “I feel like we’ve done everything we could.”
