The FiveThirtyEight Senate model is launching Wednesday. We’ll be rolling it out in stages, with additional features, functionality and further methodological detail. We’ll also be unveiling our new set of pollster ratings and publicly releasing our database of all the polls used to calculate them. So there’s a lot more to come.
But if you’re looking for a headline, we have two. First, Republicans are favored to take the Senate, at least in our view; the FiveThirtyEight forecast model gives them a 64 percent chance of doing so. CONT.
