Would the last Republican please turn out the light?

Rico says that's an old "light at the end of the tunnel" joke from the Vietnam era (thus showing his age, yet again), but it applies:

Former Massachusetts Governor William Weld, a Republican, announced this morning his support for the Democratic nominee for President, Barack Obama. Weld’s endorsement comes a day after former Bush press secretary Scott McClellan and the former Governor of Minnesota Arne Carlson, also a Republican, announced their support - separately - of Obama’s candidacy.
In a statement Weld said, “Senator Obama is a once-in-a-lifetime candidate who will transform our politics and restore America’s standing in the world. We need a president who will lead based on our common values and Senator Obama demonstrates an ability to unite and inspire. Throughout this campaign I’ve watched his steady leadership through trying times and I’m confident he is the best candidate to move our country forward,” he said.
