Will the Levee Break?

The key point is that African-Americans, who overwhelmingly vote Democratic, are highly concentrated in a few districts. This means that in close elections many Democratic votes are, as political analysts say, wasted — they simply add to huge majorities in a small number of districts, while the more widely spread Republican vote allows the G.O.P. to win by narrower margins in a larger number of districts.
My back-of-the-envelope calculations suggest that because of this “geographic gerrymander,” even a substantial turnaround in total Congressional votes — say, from the three-percentage-point Republican lead in 2004 to a five-point Democratic lead this year — would leave the House narrowly in Republican hands. It looks as if the Democrats need as much as a seven-point lead in the overall vote to take control.
...
But what’s that howling sound? Every poll taken this month shows the Democrats with a double-digit lead in the generic ballot question, in which voters are asked which party they support in this election. The median Democratic lead is 14 points.
And here’s the thing: because there are many districts that the G.O.P. carried by only moderately large margins in recent elections, a large Democratic surge — one only a bit bigger than that needed to take the House at all — would sweep away many Republicans holding seats normally considered safe. If the actual vote is anything like what the polls now suggest, we’re talking about the Democrats holding a larger majority in the House than the Republicans have held at any point since their 1994 takeover.
So if the Democrats win, they’ll probably have a substantial majority. Whether they’ll be able to keep that majority is another question. But be prepared to wake up less than four weeks from now and learn that everything you’ve been told about American politics — liberalism is dead, whoever controls the South controls Washington, only Republicans know “the way to win” — is wrong. (Are we seeing the birth of a new New Deal coalition, in which the solid Northeast takes the place of the solid South?)
