I needed to kill a little time this morning, so here’s a comparison of three different polling averages for the presidential race. I’ve stretched them out so that all three are roughly to the same scale. The Pollster model shows a very steady race, with just a little tightening but no real trend for either candidate. Upshot and 538 both show significant tightening, but with Hillary Clinton still in a solid lead with only 48 hours to go.
Who’s right? We’ll probably never know. If Clinton wins by, say, four points, all three will most likely be able to say they were within a point of the final number. On the other hand, if Clinton wins by six points, then Pollster was clearly closer than the other two. If she wins by one point, then the Upshot was closest. Exciting, isn’t it?
