For somebody not running for president, Gov. Chris Christie is spending an awful lot of time in New Hampshire.

Christie made his second visit to the first presidential primary state for the second time in little more than a month, and promised to be back again.

"I'm going to be up here often to help Walt (Havenstein) as much as I possibility can," he said.

His official business there is to raise money for the upcoming gubernatorial race, but the trips have offered the opportunity to lay the groundwork for a possible 2016 White House bid.

Christie's upcoming schedule is packed with stops in key states and the chance to make more inroads.

Meanwhile, Democrats have shifted their Christie criticism strategy from Bridgegate to the New Jersey economy.

"If he wants to come here and sell that fiscal record as the model of good governance, then we'll buy the next plane ticket," said Democratic National Committee spokesman Mo Elleithee.

Christie is defending himself, though, saying he inherited 'a moribund economy.'

Today, the governor will be in Parsippany for an Executive Order signing, followed by an open press availability.
