It’s not always fun being the frontrunner: Newt Gingrich came under serious attack from Ron Paul and Michele Bachmann in Thursday night’s Republican debate. They attacked him, in particular, for the $1.6 million he received from Fannie Mae and Freddie Mac. “I did no lobbying of any kind for any organization,” insisted Gingrich, who also responded to questions about his inconsistency by saying “I do change things when conditions change.” Mitt Romney mostly avoided Gingrich, and took a few tough questions of his own. Moderator Chris Wallace read off a list of issues on which Romney has changed positions: guns, gay rights, and abortion. Romney replied that Wallace’s list was wrong and that he’s only changed his mind on abortion. “I've learned over time,” he said. “Like Ronald Reagan and George H.W. Bush and others ... sometimes I'm wrong."
