Who said anything about ALL GOPers losing in the midterms?
Oh wait, YOU did!
All GOPers don’t need to loose in the midterms. All that is needed is for enough GOPers(to use your term), to lose in the midterms for the Democrats to take over The House. Say “Hello” to Speaker Pelosi.
Right now the Democrats already have the advantage in taking over The House if Representatives. If Kavanaugh is not confirmed, forget about retaining The House. It’s that simple really.
Pelosi wouldn't be the Speaker, even IF the Dems take the House, which they are NOT going to do!
And IF Kavanaugh isn't confirmed, which you are guessing at, that'll just make GOP voters even MORE willing to vote for GOPers, to spite the damned DEMS!
And no, the DEMS aren't going to take the Senate either.
