Romney is considered to have a home-field advantage in the Granite State. He owns a home in New Hampshire and served as governor of neighboring Massachusetts.

While Romney’s front-runner status in New Hampshire has never been in doubt, Gingrich had closed the gap in recent weeks. In November, Gingrich secured the endorsement of the influential New Hampshire Union Leader newspaper.

Gingrich’s support in New Hampshire however appears to have evaporated, along with his support in Iowa and in the national polls.

According to a PPP poll released on Monday, Gingrich's support fell sharply in the Hawkeye State, moving him from first place to third place. And a CNN-ORC poll, also released on Monday, shows Romney surging 8 points to tie the former House Speaker for first place among the GOP field nationally.

Only a week ago, Gingrich led in three of the first four early-voting states. The most recent polls diminish Gingrich’s lead to only in South Carolina and Florida.

Huntsman, who relocated his headquarters to New Hampshire and is staking his campaign on the state's primary, moved into double digits there for the first time.

This story was corrected to reflect that Newt Gingrich won the Union Leader's endorsement.
