There can be no other explanation.
I wanted Moore to step down a month ago, precisely so a real conservative could run for the seat and defeat the Democrat. That, obviously, will not occur, and Alabama Republicans are stuck with a lawless hypocrite who will be the subject of an ethics investigation as soon as he is seated. That's reality, whether you like it or not.
He may win, or he may not, but conservatives and the GOP lose either way. No, I am not happy about that.
