The Minority Vote in Battleground States

From the Washington Monthly, posted 10/27:

Republican pollster Tony Fabrizio has just finished a survey of 12 battleground states and finds Bush and Kerry tied with 47% of the vote apiece. But when he weights for minority turnout based on the 2000 exit polls, Kerry is ahead 49.2%-45.7%. And when he further updates the weighting to take into account the most recent census results, Kerry is ahead 49.9%-44.7%.

Suddenly the Bush campaign's obsession with challenging voters in minority neighborhoods makes a lot of sense, doesn't it? Their own internal polling is probably telling them the same thing that Fabrizio's poll says: unless they somehow manage to keep the minority vote down, they're doomed.
