“Gallup has me down by three points, and other polls have me trailing, tied or with a slight lead,” the president said. Why are we right and they are wrong?”The best campaigns don’t bother with national polls — I’ve come to hate public polling, period. It included state tracking polls and nightly calls from volunteers, but no national tracking polls. This is why campaigns no longer pay much attention to public polls, which often use conversations with just a few hundred people to make predictions about the entire electorate. They look at public data sets that list each registered voter’s name, address, party registration and election participation history.
