What has happened will cost us dearly, but the GOPe didn't make a mistake. They worked hard to make sure that Moore lost. They are a wing of the Uniparty and would be much happier being the token opposition to actually representing the GOP voting base. Mitch McConnell would be very comfortable being the Minority Leader rather than having to fight for conservative principals.
Correct. Watching the Republicans campaign for a majority is sort of liking within a dog chase a car.
Even if the dog were to somehow catch the car, what the hell is it going to do with it? It hasn't clue.
