My son has launched another political game — and this one is especially dangerous if you think you know what Americans believe.It’s called Pollster, and the idea is simple: You’re shown a real polling question and have to guess the percentage of Americans who gave a particular answer.The questions come from major polling organizations and some of the answers are much harder to predict than you might expect.Like his other games, it only takes a few minutes to play. But it’s surprisingly addictive.It joins Yea or Nay, where you try to predict how senators voted on key legisation, and Split Decision, his Supreme Court game.
