He may. Romney is the establishmentarian candidate. If he gets the nomination, Washington won't really care who takes the general election, the status quo will win either way. Gingrich, with all his volatility, is now the leading antiestablishmentarian in the race, and the votes cast in the primaries are reflecting the public's revulsion with business as usual. It isn't that the voters are happy with Gingrich, it's that they can't stomach another Dole or McCain, which is what Romney represents.
