It is not the Democratic Congress that has the disapproval rating. It is Congress, the whole damn thing that has the rating.
But this does not mean doodly-squat, because the people do not vote for Congress; they only vote for one senator and one representative, and it is only that vote that counts, whatever the motive.
I expect many more Republicans to be thrown out than Democrats. I would also favor this, because the GOP has been beyond useless for many years now.
And no, no matter who wins, the new congress will NOT be more Christian by any definition, nor will it result in less government. Perhaps you would have better luck in Estonia, CU4.
You should have been born an Est.
