Job’s Anger has taken the leap and endorsed Bill. 

He gives a great summary of why - at least at this early stage - he doesn’t feel he can support the other likely candidates:

All of these are admirable Democrats, and they are serving their country well. But at this time, I cannot support any of them. To me, they all carry some negative baggage.
Clark is simply too conservative for my taste. Gore ran a poor campaign last time, and there’s no reason to believe he would do any better in a second run. Clinton and Edwards have moved so far to the center that I’m not sure what they believe in anymore. Obama is simply too inexperienced, and after his vote on the bankruptcy bill, I don’t think he understands the needs of working class and poor Americans.

These echo many of my own reservations about the others.  And his reasons for supporting Richardson are virtually identical to my own:

So, I have opted for competence. I support Bill Richardson because I believe he is the most competent of the major candidates. He is a successful governor, and was just re-elected by the citizens of New Mexico. He understands the problems that our states face and could be a valuable asset in helping to solve those problems.
He also understands America on the national level, having served for 15 years in the U.S. Congress. He wouldn’t need time to figure out Washington as most governors would, and could hit the ground running if elected president.
Even more impressive, he has been effective on the world stage. He has been America’s ambassador to the United Nations, and several presidents have used his diplomatic skills to trouble-shoot thorny international problems. He has proven he can talk to anyone and bring them peacefully to reasonable actions.
Richardson is also an excellent campaigner. When you listen to him speak, you come away with the impression of a man with common sense, who truly understands America’s problems and has rational solutions to those problems. I believe him to be the most competent of all the candidates.

I’ve done politics in a lot of jurisdictions, including D.C.  I remember being impressed with Richardson back during the Clinton years, particularly with his performance on the international stage.  And if the last six years have taught us anything, it’s that the entire stage is international - and in light of America’s recent performance, everyone from season ticketholders to the peanut gallery patrons want their money back.  At the moment, at least, I’m putting my money on Bill, too.
