New Hampshire’s four electoral votes are in play:

Four years ago, President Obama easily won the Granite State, but after major Republican gains in 2010, Romney’s campaign is optimistic about its chances in New England’s flinty, independent neighborhood. Over the past few months, they have opened multiple offices and call centers across the state.
“This is a state that can swing dramatically,” says Ryan Williams, a Romney adviser and a former aide to New Hampshire governor John Sununu. “We think it’s going to be close and that we can win here, especially since the governor has been competing in the primary for a number of years.”

In the polls, Romney has recently closed the gap. The latest New Hampshire poll, published by WMUR, shows Obama leading Romney, 49 percent to 45 percent; but back in WMUR’s April poll, the president led Romney by nine percentage points.
