FILE - In this July 25, 2012 file photo, Sen. Marco Rubio, R-Fla. speaks in Washington. The list of Paul Ryan's mentors includes some of the biggest conservative names of recent decades, including Jack Kemp and Bill Bennett. Yet the ideological roots of Mitt Romney's vice presidential running mate, including his emphasis on individual responsibility and small government, sprouted from Ryan's small-town Wisconsin upbringing and a libertarian college professor. His outlook and career also have been nurtured by a devotee of supply-side economics who is now a top aide to another rising Republican star, Sen. Marco Rubio of Florida.
