Nick also proffers the following Senate analysis: "in the states with the ten most competitive Senate races, Obama does better than Clinton in eight of them; only Kentucky and Louisiana are better for Clinton." I don't know how well this polling will hold up, but I think this is a crucial question. The issue is not so much coattails as it is anti-coattails. If this starts to shape up as a good year for Democrats, "let's not give Obama/Clinton a blank check" will be a persuasive argument to some voters in states where Obama or Clinton is unpopular. You want to minimize the number of states like that.
