The House may be all but lost, but Democrats are looking more likely to keep the Senate, says FiveThirtyEight’s Nate Silver. He says the chances of a GOP takeover are 16 percent, down from 19 percent over the weekend after polls showed Democratic momentum in West Virginia and Colorado. In the latest West Virginia poll, Democrat Joe Manchin leads by six points. Meanwhile, Colorado’s Senate race is “the closest in the country,” according to Silver. Two polls show Republican Ken Buck and Democrat Michael Bennet in a dead heat.
