By definition, didn’t John McCain collude with Russia against Trump? He did.
When it came out that not only had McCain peddled this "dossier" to his Obama contacts at the FBI, but had sent a personal aid on a plane over the Atlantic to personally retrieve a hard copy of it in Europe, McCain immediately knew he had been exposed, and went into damage control.
Using his media skills of appearing on Sunday news programs hundreds of times, he knew he had to the negative information "out there" before he as immersed in scandal himself. He also knew the media would be friendly to him. So he threw out some wild lines about how what a "good citizen" he was and that peddling this crap was something "any loyal citizen would do."
Why do republicans allow this?An important question.
I think the answer is, they want to remove President Trump through impeachment but don't want to get their hands dirty, lest it make their voters angry. Their comrades in the "Democratic" wing of the entity that rules over us understand their dilemma, and are more than happy to play "bad cop" to the congressional GOP's "good cop".
All the pieces are in place for a (perfectly legal) coup, as long as the corrupted Mueller investigation is allowed to run to completion.
Note that Paul Ryan, in his only passionate remarks so far about the "Russia" nonsense, vouched for Mueller's integrity and impartiality.
Ryan is the frontman for Romney and Bush, and is the key player in the conspiracy.
As soon as Mueller indicts Trump, a "shocked" Paul Ryan, "with a heavy heart", will announce that Trump has to go. All Ryan needs are 25 GOP votes (I presume all 193 Democrats are on board), and he surely has them in his pocket already.
Once Trump's trial in the Senate begins (if they even allow him the courtesy of a hearing), the 67 votes to remove him are certainly there. After all, the Democrats fear Trump but the Senate Republicans truly hate him - he stole their party, and they want it back.
Notice how Mueller is practically begging to be fired. I expect him to escalate his misbehavior after Labor Day. Either Trump allows himself and his whole family to be indicted, OR he saves Mueller the trouble by firing him - in either event, Ryan is now free to uncloak and issue the indictment the Senate is dying to receive.
The one way out (and I've been saying since January Trump had six months to do this, sorry DJT, time's up) is for Trump to renounce the Republican Party and announce that, since the Congress is unable to act in the American people's interest because of corruption that HE will personally designate 435 candidates for the House and 33 for the Senate in 2018 that will support his agenda.
This burns his bridges, and COULD lead to his removal - but it also would be such a potent threat that it could stay Ryan's (Romney's and Bush's) hand.
