Bush has ramped up his criticism of Trump as he fights to reverse his slide in the polls over the past few months. He was the only candidate who directly criticized the GOP front-runner's call to ban Muslim's from entering the U.S. during this month's GOP debate. And many of his recent campaign ads focus on Trump.
 
Bush's best chance at toppling Trump is the upcoming primary election in New Hampshire, where he's locked in a logjam of establishment candidates. He is tied for fifth in RealClearPolitics' average of recent Granite State polls, but that's just 5 points out of second place.
