Well, Bill Kristol is reporting that Powell will be endorsing Obama at the Democratic Convention.

Yes, a big help for Obama.

But, no, not unexpected. Powell always struck me as a Lincoln-Chafee-style RINO, a nominal Republican ONLY when it is clearly in his interest to be so. I would distinguish this category from the liberal, but sincere Republicans like Chafee, Snowe, etc.
