Paul has already stopped actively campaigning, conceding that Romney will be the GOP nominee.

But his campaign is still eager to shake things up at the national convention and influence the direction of the party.

Paul looks likely to have about 200 delegates on the floor in Tampa that are able to vote for him, along with a few hundred others that are considered his supporters but are bound to vote for Romney.

Dave Cushman, a new GOP state central committee member, told the Des Moines Register that members of the liberty movement want to use Paul's presence to strengthen the party.

"The movement has a huge responsibility when it goes to Tampa to show Iowa we're a real movement and we're not there to be rabble-rousers," Cushman said.

"The goal is not to embarrass the party. The goal is to make the party stronger and broaden the base, and walk the Republican talk."
