Celebrities are a common sight on the campaign trail and often bring their fan base -- and Twitter following -- with them in support of political issues and candidates. In 2012, President Barack Obama appeared on the campaign trail with performers Katy Perry, Dave Matthews, Pitbull and Bruce Springsteen.

Some of the big names are getting in on the ground floor of the 2016 presidential race -- several celebrities have already signaled their support for some of the potential candidates.
