Why did Liberal Marxists sabotage Newt Gingrich's presidential campaign from the inside?

LMAO just 2 weeks ago you guys were singing his name. Now he's a liberal? You just can't get over the fact that Republicans have NO ONE credible to run against Obama and that you all look fools for supporting Gingrich in the first place. No one put a gun to your head and forced you to praise Gingrich.
