Bob Kerrey Back to the Senate?

I was surprised to read that former 9/11 Commission member and former Senator of Nebraska, Bob Kerrey is being recruited for, and is apparently highly interested in, another Senatorial run. I didn't think he even still lived in Nebraska. I suppose this should be counted as good news, although I wonder about his prospects. And even though he's a bit of a gadfly for progressives, having an extra vote for majority leader wouldn't be bad.
