Portsmouth, New Hampshire (CNN) – The Romney campaign is considering about 20 names for the presumptive GOP candidate's vice presidential slot, said top campaign adviser and former New Hampshire Gov. John Sununu.
"I know that the bowl has about 19 or 20 little folded pieces of paper in it, and they keep shaking the bowl," Sununu told reporters in New Hampshire Monday.

Romney is campaigning with one possible pick Monday – New Hampshire Sen. Kelly Ayotte, whose November endorsement of the former Massachusetts governor gave his campaign conservative credibility in the early voting state.
Sununu said Ayotte is a "strong candidate" but comes with a negative: the fact that both she and Romney are from the Northeast.
Romney has appeared with a series of vice presidential potentials in recent weeks – fueling speculation over his eventual choice – but the former governor has said his search is still in the early stages. Longtime aide Beth Myers is heading that process.
Sununu downplayed a suggestion the Monday New Hampshire event could be a rehearsal for a Romney-Ayotte ticket.
"He's in a battleground state with a very important elected senator from a battleground state," Sununu said. "When he goes to Ohio he's got [Sen. Rob] Portman on the stage, and [Gov. John] Kasich on the stage. When he goes to Virginia it's [Gov. Bob] McDonnell. When you go to the battleground states you get as much of the powerhouses as you can on the stage."
The feisty politico declined to endorse any vice presidential candidate, joking: "I have learned a long time ago that sometimes my endorsements can doom somebody."
He predicted Romney would win New Hampshire by "three or four points" in the fall.
