Andrew Gelman on How Americans Vote | FiveBooks | The Browser: "The idea is that these people know enough about us so that they can manipulate our vote. Realistically, political consultants nowadays know a lot about us, and they do try to convince us. There are two kinds of people they follow. One is people where they know who they’re going to vote for, but they’re not sure that they’re going to vote. The other is people who are very likely to vote, but you don’t know which way they’re going to vote. The first type of person they try to mobilise just to turn out and vote, and the second kind of person they try to persuade. They’re pretty good at knowing who people are. In fact, at this point, a lot of this is just a question of resources. To the extent they have resources they will go out to people and call you on the phone. If they think you’re already likely to vote for a certain candidate, they’ll try to find somebody to knock on your door and convince you that it’s an important election and it’s worth voting for. In some sense it’s not as mysterious or conspiratorial as it’s made out to be in that book."
