LUTZ, Fla. (January 29, 2012)--Newt Gingrich is calling GOP rival Mitt Romney a "pro-abortion, pro-gun control, pro-tax increase liberal."

Gingrich made the comments Sunday outside a church in Lutz., Fla., two days before the state’s pivotal presidential primary.

Gingrich trails Romney in Florida and has been calling the former governor a Massachusetts moderate, but now Gingrich is adding the liberal tag to his criticism of his 2012 rival.

Gingrich also went after Romney during two television interviews Sunday morning.

He said Romney "has a basic policy of carpet bombing his opponent" and that the "old establishment" in the party is trying to block Gingrich's path to nomination.
