Newt Gingrich, on Fox News, saying he'll spend his own money, "if necessary", to keep the campaign going.
Bonus: He says he has "no incentive" to get out of the race (although wouldn't spending your own money be an incentive?).
GINGRICH: I have no incentive to get out, because I have a set of ideas that include $2.50/gallon gas etc., So I have every incentive to stay in.
BILL O'REILLY: But you don't have any money. You'll spend your own money?
GINGRICH: If necessary, but that's not the point. We are raising some money.... I'm open about it. I don't mind telling people we need to raise money.
