If all else fails for the Republicans, they are counting on the tactic of limiting voting by poor and non-white voters. Some bright spark has siezed on the mortgage crisis as a sort of natural selection device to keep people who might want regime change away from the polls. To cut to the chase, some state Republican parties are arming their poll-watchers with list of recently foreclosed properties matched to the electoral rolls, so someone who is, say, dispossessed and evicted from their home in the weeks leading up to the election can be disenfranchised on the basis that they haven't established a new home yet and updated their address. (Some states don't allow you to update your address for quite a long period before election dates, making this tactic so much easier to deploy.) I think the story says it all; there is nothing I can add.
