If there was 100 people that worked under reagan and one or two endorsed Obama you would make a thread about it. Oh wait you just did.
Neo, far more than "one or two" have endorsed Obama. In fact, I posted the list of Republican endorsements (and didn't include press endorsements) and the list of Republicans went on for two pages, from Colin Powell to Scott Mclellan on down.
If there were 100 people who worked under Reagan, only one of them would be Chief of Staff, but go ahead, show your lack of judgment by acting like Ken Duberstein was no more important than the guy who emptied Reagan's wastebasket at night.
