--Former House Speaker Newt Gingrich told a conservative Christian radio show that he was having an affair at the same time he was leading Republican attacks on then-president Bill Clinton over the Monica Lewinsky scandal. But he says he's no hypocrite, since the fight was technically not about Clinton's infidelity but rather the fact that he lied about it in court. Gingrich told Focus on the Family's James Dobson "I drew a line in my mind that said, 'Even though I run the risk of being deeply embarrassed, and even though at a purely personal level I am not rendering judgment on another human being, as a leader of the government trying to uphold the rule of law, I have no choice except to move forward and say that you cannot accept ... perjury in your highest officials."

--A group of Massachusetts Republicans is ripping former governor Mitt Romney - vowing to expose his flip-flops on issues from abortion to taxes to gay rights. The Massachusetts Republicans for Truth plan to attack the governor's record online and on the airwaves, and will release "The Romney Report" on its website on Monday. The group's founder says about 40 party members have joined so far, and says Romney has changed his position too many times to be credible, adding "If you don’t have any core beliefs, you shouldn’t be president of the United States."

--Arizona Sen. John McCain hosted a fundraiser and question and answer session in Rudy Giuliani's home turf yesterday. He called Giuliani an "American hero," but brushed off Rudy's surge in the polls, saying "This campaign ... is still in spring training. The results will be based on record and vision and a lot of that will come out in the debates and the forthcoming campaign. We are very happy where we are." He also said he'd welcome Nebraska Senator Chuck Hagel if he decides to enter the race, saying "I respect Chuck's decisions and views but it will not impact our friendship and our relationship in the slightest."

--Speaking of McCain, he's expected to announce the endorsement of North Carolina Senator Richard Burr in Charlotte. The Politico reports that Burr ripped McCain over his efforts to raise taxes on cigarettes and bring tobacco under FDA regulations in 2000, when Burr was still a congressman -- saying "The Southeast never forgets anyone who affects their livelihood." Burr may not have forgotten, but he seems to have forgiven.

I--llinois Sen. Barack Obama won the endorsement of former Clinton administration official Philip W. Johnston, now the chairman of the Massachusetts Democratic Party. And New York Sen. Hillary Clinton continues to battle Obama for big donors in Obama's hometown of Chicago.

--Former North Carolina Sen. John Edwards locked up the support of all 7 of his home state's Democratic congressional delegation. Of course, Edwards couldn't even carry the state in 2004, and a recent poll had him trailing Hillary Clinton with the support of just 13.5% of North Carolina voters.
