If those polls translate across (i.e. upballot) it won't just hurt Trump; Joni Ernst is toast too.
Which in turn means, if they win senate seats in Colorado (which they almost certainly will, Hickenlooper is currently serving Gardner his arse on a plate), Maine and NC (where they have truly excellent chances, thanks in no small measure to the incumbents' gutless ernabling of all that Trump has done), then the Senate is tied even if they lose in Alabama. Plus, they have a terrific chance of the open seat in Georgia.
Mind, if they than managed to unseat those ghouls Purdue, Cormun and Linbdsey effing Graham, I'd be practically floating up to the ceiling - but I don't want to get those hopes up.
