Kentucky Sen. Rand Paul narrowly won the presidential straw poll that closed out this year's Conservative Political Action Conference.

Paul won with 25 percent of the vote. Florida Sen. Marco Rubio finished just behind him with 23 percent. Former Pennsylvania Sen. Rick Santorum was third with 8 percent.

Even though the next election isn't until 2016, Paul has already said he's seriously considering a presidential run.

Nearly 3,000 people participated in CPAC's unscientific online poll.

Paul's father, former Texas Rep. Ron Paul, won the poll in 2010 and 2011, while former presidential nominee Mitt Romney took the honor last year.
