Sounds about right, if he's right there are limits to what they will do, lines they won't cross. There is a point where they are gonna publicly fold, all a show for the base so the current leadership can have some future power in the party. When the republicans lose bigly (a Donaldism) in the midterms you can imagine the next crop of primary candidates the current base will throw up, now imagine if the current leadership was seen to help bring Donald down? They are gonna have to impeach him, what is coming out will leave no choice, the base will flip out on them, political parties can go to Hell, look at what's gonna happen to these pricks.
I dunno if not running again will protect some of these fuckers from the FBI next year. The democrats won't lift a finger to protect them and nobody will need to encourage the FBI or the lifers in the justice department to go after these pricks hammer and tongs in hand. Donald will be in jail and president Pence might be fighting impeachment and jail too, so he might not help them much either. If they are in bed with the russians they should worry, the old rules don't apply here, they threw the rule book in the ditch. When the country gets back on it's feet and has a chance to have a real close look at this mess, things could get even worse for some people.
This business is gonna go on for years with hearings and commissions etc and so it should. This is the proper role for such things, no benghazi here, truth, not bullshit will be the result. Look at what happened to California when they got rid of the republicans, they went from "ungovernable" a few years back to top of the fucking world today. Its possible for America too, now's your chance to do what California did, this might really be an opportunity...
Sometimes it's useful to take a longer view.
