Add former Bush press flack and lifelong Republican Scott McClellan to the long list of unlikely Obama endorsements.

WaPo:

Former White House press secretary Scott McClellan, who angered many Republicans earlier this year with a memoir criticizing President Bush, said today that he's voting for Democratic presidential candidate Barack Obama.

McClellan told CNN that Obama's message "is very similar to the one that Governor Bush ran on in 2000," apparently referring to the current president's early pitch as a reformer and a moderate.

"From the very beginning I have said I am going to support the candidate that has the best chance for changing the way Washington works and getting things done and I will be voting for Barack Obama," McClellan said during the interview, which was taped for the Saturday broadcast of a new CNN show, "D.L. Hughley Breaks the News."
