Jennifer, the answer to your question — how does Barack Obama redraw the map? — is that, if he does his job right, he won’t have to redraw the map. A vote against him in a primary is not a vote against him in the general election. These are, after all, Democratic primary voters, and it is to be expected that most of them will vote for the Democratic nominee. That is good news for Obama, because the turnout in these primaries has been so astonishingly high. If he gets 90 percent of the votes cast in the primaries, he will begin election day with 33 million votes in his pocket. There’s never been anything like this.

What we don’t know is whether the rejection of Obama in the states where he has received a shellacking by Democrats is suggestive of the attitudes of independent voters. There is some reason to believe it probably does, given just how liberal Obama is, but we just don’t know yet. In that possibility, there is McCain’s opportunity.
