Mitt Romney has reached the halfway mark in filling his $800 million campaign war chest, a leading fundraiser for the campaign said on Thursday.

Woody Johnson, the owner of the New York Jets, said the campaign’s joint committee had raised nearly $400 million, which was about half of its goal.

“We’re about half-way through our fundraising, and so if you feel tired now, you gotta go take a couple vitamins because we’re gonna really have a strong push to the finish line,” Johnson said at a fundraiser with Romney in Manhattan. “It’s a little bit like chopping wood. You look over at your pile and you can actually see how it looks.”

Romney supporter Emil Henry, a former official at the Treasury Department, also heralded the Romney fundraising machine.

“The governor is out raising a sitting President of the United States,” Henry said to loud applause.
