You guys really haven't been paying ANY attention. The GOP is folding behind trump, they aren't standing up against him. Those in the GOP who oppose him are retiring or dying, or will be primaried away.
The house as it stands will NEVER vote to impeach, and the dem's just don't have the ability to take it in 2018. Even if they do, there aren't enough republican senators willing to bring a vote to convict to 66.
As for Muehler, ptckkt. He will certainly issue low level indictments, maybe even to trums family, but not likely against trump himself. Even if he does, Trump still has the pardon. And this SCOTUS isn't going to take it away. State law? Won't be prosecuted until he leaves office. The courts won't allow a criminal trial against a sitting president to proceed at the state level.
You voted for him, or enabled his election, and now we are all stuck with him. If you are stupid enough to run bernie against him in 2020, he will get another 4 years.
Muehler will do whatever it is he is going to do, and it will have zero impact on trump. If anything, he will burrow in deeper.
