Like I said, points 4 and 5 are your strongest ones for swinging voters who would otherwise tend to vote Rat. The distrust that Hispanic voters have for Obama has been clearly demonstrated in exit polls, and since we've had the unusual circumstance of having a truly contested primary battle through all fifty states and the territories, we've got a good read on what role identity politics is going to play in this election. We're also starting to see a lot of middle-aged women whining and getting bitchy as Hillary's options are narrowing.
But people who are already suspicious of Obambi will remain that way. I would suppose a few people in the early caucuses and primaries who did vote for him have changed their minds about it, and had wished they had voted for the Beest, but when it comes down to it, they were definite Democrat voters (no Operation Chaos mischief, since Republicans had their own quite active contest going on), and will find a way to resolve their suspicious about Obama by finding McCain to be worse.
