Christie is considered the frontrunner in the Republican primary to take on Gov. Jon Corzine (D) in the general election this November.

In a statement, Romney applauded Christie's conservative record.

"Chris Christie is a strong conservative voice for balanced budgets, low taxes and more jobs," Romney said. "He will bring badly-needed change to state government."

The New Jersey gubernatorial race is considered an indicator for whether the GOP can recover in New England. Christie is a top recruit and is leading Corzine in recent polls.

Romney's PAC, the Free and Strong America PAC, has been a fundraising machine, so it'll be interesting to watch how much money it funnels to Christie's campaign.
