The crazy thing is that they aren't wrong. I don't think enough Gaffers spend enough time talking to these Republicans, but I do. And, that is exactly how they think, everything justifies the end goals. I've heard people literally say, "so what if Trump is in league with the Russians? It's better than corrupt Hillary and at least he might turn them into an ally."
To them its pretty simple, all this Russian stuff is foreign shit that doesn't affect their daily lives along with Trump's personal indiscretions. Who cares about Russia or Trump's taxes? If the Dems get back in more babies will be killed, my taxes will go through the roof, my healthcare premiums will double, the gays will be able to run amok, I won't know which bathroom to go in, Mexicans will take every last job in America, Christianity will be replaced with secular and/or Muslim rule, and I won't even be able to speak my mind without being labeled a racist or homophobe thanks to PC culture.
That is who is supporting these Republicans.
The Attorney General. Of course, he/she can decide not to.
