Gingrich calls Romney "Massachusetts moderate"

Continuing his war of words with Mitt Romney, Newt Gingrich on Thursday accused his chief GOP presidential rival of being a "Massachusetts moderate."

"When a Massachusetts moderate says I'm not conservative, it makes me want to laugh when he goes down that road," Gingrich told radio show host Tony Powers, responding to the former Bay State governor's frequent charge. "When a Massachusetts moderate says Newt Gingrich is not conservative enough, other than break up laughing I don't know what the correct response would be."

Gingrich also criticized another rival, Rep. Ron Paul, who also has run ads critical of the former House speaker. 

"Paul's case is different because he believes in legalizing drugs ... [he] thinks it's okay for Iran to have a nuclear weapon and believes Americans are responsible for 9/11, which makes no sense,"  he said.

And he took a shot at President Obama, who in a recent CBS-TV "60 Minutes" interview said he would put his legislative and foreign policy accomplishments in his first two years against any other president except Lyndon Johnson, Franklin D. Roosevelt and Abraham Lincoln.

"He skipped past [Ronald] Reagan, who liberated Eastern Europe when [Obama] can't even liberate a park in New York City," Gingrich said, in reference to the Occupy Wall Street's encampment in Manhattan.
