Kentucky Sen. Rand Paul (R) has narrowly won the 2013 Conservative Political Action Conference straw poll, picking up where his father left off at the conservative confab.

Paul won 25 percent of the vote in a field of potential 2016 GOP presidential contenders, clearing the support level of second-place finisher Sen. Marco Rubio (R-Fla.), who took 23 percent. Former senator Rick Santorum (R-Pa.) took 8 percent, while New Jersey Gov. Chris Christie (R), who was not invited to CPAC, took 7 percent.

The first-term senator's win was widely expected, especially given his father's past successes in the CPAC straw poll. Rep. Ron Paul (R-Tex.) regularly attracted huge crowds of devoted supporters at CPAC and won the straw poll in 2010 and 2011.
