As Gingrich Leaves Stage, Obama Campaign Says Thanks For The Memories

On the day Newt Gingrich finally gets out of the way of Mitt Romney, the Democrats have offered a parting gift of sorts from the former House speaker to the presumptive Republican nominee.

President Obama's re-election campaign on Wednesday launched a Web ad titled: "Newt Gingrich: Frankly, not Mitt Romney's biggest supporter."

The 90-second ad relives some of the less-than-flattering statements Gingrich made about the former Massachusetts governor during the course of an often nasty Republican primary fight.

It's not clear whether Gingrich will formally endorse Romney when he suspends his campaign Wednesday afternoon in Virginia. But on Tuesday, while thanking supporters in his own Web ad, Gingrich said: "All of us have an obligation, I think, to do everything we can to defeat Barack Obama."

Romney is campaigning in Virginia on Wednesday and again Thursday, when he is scheduled to appear with that state's Republican governor, Bob McDonnell, who is on a long list of potential vice presidential choices.
