Whatever you think of Powell, I don't think anyone can legitimately say that Powell has ever done anything he didn't think was in the best interest of this country's security. He's not an economics guy, but he was one heck of a general and I think a very good Secretary of State. The fact that he basically quit put him in line with some of my personal friends and first cousins who were fairly senior officers in Iraq at the same time (Majors, Lt Cols, and Cols) and some of the things they told me they disliked about the Bush administration when they got back. And these friends and relatives are "good conservative Texas boys" (and one girl) who didn't like what the Bush admin was not doing in Iraq. So, I hold Powell in high esteem.
I have a hard time getting over Obama's upbringing and his name for obvious reasons. But, Powell knows the man if he had a single concern about it, he would have never endorsed him. So, that makes me feel a lot better about the man who is about to win this thing. I won't vote for him, but maybe it'll work out ok.
