Former Massachusetts Gov. Mitt Romney (R) leads Republican presidential contenders among the Granite State’s likely GOP voters, drawing the support of 36 percent of them.

Bachmann is the only candidate other than Romney in double digits; 11 percent of New Hampshire Republicans said they support the three-term congresswoman as the nominee, up from 3 percent in early May.

The poll was conducted over the weekend, just as Bachmann was preparing her formal announcement on Monday in Iowa. A poll by the Des Moines Register showed Bachmann at second place in the state, at 22 percent to Romney’s 23 percent.
