Sen. Marco Rubio is no longer the favorite to picked as Mitt Romney's running mate, according to the online oddsmakers.

Rubio is now third choice behind fmr. Minnesota Gov. Tim Pawlenty and Sen. Rob Portman from Ohio.

Sportsbook.com lists Pawlenty at 3-to-2 odds. That means that if you bet $100 on Pawlenty to get picked, and he gets picked, you would win $150 plus your initial investment of $100 or $250 total.

Portman is second at 3-to-1 odds. Rubio is third at 4-to-1 odds.

Former U.S. Sec. of State Condoleeza Rice is fourth at 10-to-1 odds along with Louisiana Gov. Bobby Jindal.
