Mark Mellman, who was John Kerry’s 2004 polllster:
“A lot of things can happen between March and November. My own view is that either one of them would win in November because the fundamentals favor the Democrats. But you have no real way of knowing who would be stronger against McCain.” Mellman dismisses the far-in-advance horse-race polls that purport to measure how Obama and Clinton would perform against the Republican nominee: “People are very mediocre predictors of their own future behavior.”
