With his 2012 White House bid, Ronald Earnest Paul is hoping the third time is the charm. A trained doctor, he also served in the U.S. Air Force and National Guard. After a few stints in the House in the 1970s and 1980s, Paul returned to Congress in 1996, where he has served Texas’s 14th district ever since. His politics are a mix of Republican and Libertarian views. Paul was born August 20, 1935, in Pittsburgh and is married with five adult children.
