Florida Sen. Marco Rubio was the undisputed favorite vice presidential choice of conservative activists gathered for the Chicago Conservative Political Action Conference (CPAC), receiving 30 percent of a straw poll vote that asked attendees who they would like to see as Mitt Romney’s running mate this fall.

Rubio – who did not speak at the conference – was followed by New Jersey Gov. Chris Christie with 14 percent and Rep. Paul Ryan, with 9 percent of the vote. Fourth and fifth place went to Kentucky Sen. Rand Paul and Louisiana Gov. Bobby Jindal (who spoke to the crowd Friday afternoon) respectively.

Virginia Gov. Bob McDonnell, who spoke to the crowd Friday afternoon, and Ohio Sen. Rob Portman, a top-mentioned VP possibility who did not attend the conference, both received less than 2 percent of the vote.

The poll’s results were much less conclusive on the question of what should drive the presumptive nominee’s choice. Thirty-two percent of the voters wanted to see Romney run with someone who could reach out to the more conservative wing of the party, 27 percent would like to see a running mate who would complement his governing and 20 percent said they would prioritize a candidate with broad national appeal, especially to minorities.
