JACKSONVILLE, Fla. -

Republican presidential candidate Mitt Romney will be campaigning in Jacksonville a day before the Florida primary, and some analysts believe it's possible that Romney may pick a running mate while in the state.

Romney is scheduled to be in the River City on Aug. 13, just two weeks before the Republican National Convention.

Some names mentioned as possible vice president's include Sen. Marco Rubio, Gov. Bobby Jindal and Gov. Chris Christie, just to name a few.

This is stirring a lot of vice president speculation. Romney could campaign in Jacksonville beside his potential running mate.

For now, voters are left guessing who it might be.

"I like Jeb Bush actually," Jeff Berry said, adding he thinks VP pick is important. "We'll have to wait and see what happens."

Romney supporter Sue Brinson said, "Well I, don't know. I like Rubio."

Some Romney supporters have their favorites picked out from a likely short list, while others are looking more toward long-shots.

"I would love to see him pick Herman Cain," voter Scott Brown said. "Herman Cain is who I would've voted for."

Voter Steve Wilder said it's a hard decision but he would pick Hillary Clinton, even though she's a Democrat.

The VP pick could prove to be important when it comes to casting ballots.

As a political science professor at the University of North Florida, Michael Binder points out that during the presidency it's a pivotal role.

"You know the vice president goes out and serves as a surrogate for the president, so it's important to have a candidate who is a good campaigner who can go out, excite crowds and get people motivated," Binder said.

Binder maintains most voters cast ballots based on the top of the ticket, but it's possible with an off-the-wall VP pick, it could sway some away.

Until then it's wait and see for who the potential vice president might be.
