I think this seat will give the Republicans the edge now. They already would have it if either AZ wasn't awful or GA wasn't a complete distaster. NH is very winnable as well, but he's just as bad as the AZ candidate in a bluer state. I think CO is hard, because the GOP is damned if they support Trump with moderates, damned if they don't with the base. So...as of today I'm predicting 0 pickups for the Democrats and 1 (NV) for the Republicans to give them a 51-49 edge. Control will come down to AZ, GA, NV, PA, WI, and OH. If NC or FL come into play then the Democrats will sweep those 6 states. Ditto for Republicans with NH or CO.
