Mike Huckabee generated a little buzz on Sunday. He told Fox News that he’s the Republican who “clearly at this point does better against Obama than any other Republican.” Mitt Romney, meanwhile, continues to focus on endorsements. He’s announced three more in Maine, bringing his total this cycle to 100. Newt Gingrich is also keeping up with the endorsement game, throwing his support to Bill McCollum’s gubernatorial campaign in Florida. Tim Pawlenty, for his part, continues to jet about. In recent days, he’s rallied GOP activists in Tennessee and tomorrow he heads to South Carolina, where he’ll lend a hand to Nikki Haley. Sarah Palin, of course, is also busy. Over the weekend, she spoke in Norfolk, Va., where she criticized Obama’s foreign policy. On Friday, she was in California, where an audio recording of reporters trashing her speech went viral.
