Paul, whose son recently won a Congressional seat of his own, led the tally with 30% of the vote. Mitt Romney came in second with 23%.
Most experts agree that the straw poll tally means little for Paul. Romney won the straw vote in 2007, 2008 and 2009 but couldn’t get close to John McCain during primary season.
According to Fox News, one CPAC official even expressed frustration that the conservative caucus couldn't pick a more credible contender - a sentiment expressed by Trump earlier in the convention.
"I think he's a good guy," Trump said on Thursday. "But honestly, he just has zero chance of getting elected. You have to win an election."
Romney and Paul were the only two contenders who reached double digits in the poll. New Jersey governor Chris Christie, who has repeatedly denied he wants the nomination, came in tied for third with 6% of the vote. Former House Speaker Newt Gingrich, who is said to be gearing up for a run, tallied 5%. Trailing behind them, the ever-outspoken Michele Bachmann, former Minnesota Gov. Tim Pawlenty and Indiana Gov. Mitch Daniels earned 4% of the tally each.
Sarah Palin, who did not appear at the convention, earned 3% of the vote.
