Harry Enten: “The fight for control of the United States Senate is really close. It’s basically a coin-flip. Democrats have a 53 percent chance of winning a Senate majority according to FiveThirtyEight’s polls-plus model, or a 52 percent chance according to our polls-only forecast. There is about a 16 percent chance, in fact, that we’ll end up with a 50-50 Senate and the presidential race will decide control. (The vice-president breaks ties in the Senate.)”
