I think the Obama campaign has two constraints. The first one is that he was selected by a process that favors the most Left wing candidate among the Democrats. He is held to their standards and policy preferences; witness the revolt among the socialists/Marxist among his supporters recently over things like Israel and how to handle the war against the Islamic jihad. Now, he can flip-flop and get away with it when it comes to supporters who are less ideologically rigid. That is especially true of those who accept that deception is part of the way you wage war. So, in his base of support that kind of buffers him from the discomfort of flip-flopping. But, there is another constraint on what he can get away with and how he can move. The independents and Middle Muddle folks. Now, there are independents who will not tolerate a candidate who is perceived to be deceptive. That’s a very hard constraint for Obama. The people who are what I call the Middle Muddle are so vapid and lazy that they would not know that they are being played if it bit them in the ass. He can get away with a lot there. Now, the question is which group is larger? The alert independents or the somnolent Middle Muddlers? If the latter, he has more wiggle room. If the former, he had better be careful.
