According to one of Mitt Romney's campaign advisors, he has about 20 names in the hat for a potential vice presidential candidate.
Romney was campaigning with one of them today, New Hampshire Senator Kelly Ayotte.
Romney has appeared with a series of vice presidential potentials in recent weeks fueling speculation over his eventual choice.
Romney sealed his spot as the presumptive GOP nominee, when Rick Santorum dropped out of the race earlier this month.
