Regardless of what Mueller comes up with, the only remedy is impeachment (unless you consider civil war an appropriate remedy).
- If the Mueller findings turn the public so against Trump to erode his base support, then Congress will vote to impeach and remove him, because it would be *their* electoral asses held accountable. They don’t care about Trump’s.
- The next part of that will be if PENCE is also found, as a part of the previous events, to have no base support. If so, he will also be impeached and removed.
- And so on.
There is no scenario that results in a Democrat in the White House prior to 2020. Eventually you end up with a Republican who is untainted by anything to do with Russia, and we don’t do “guilt by association” in the US.
As for the shibboleth “somebody should do the ‘right thing’”, well……suffice to say that the supporters of the two parties will not agree on what the “right thing” is.
So, how do you decide what the “right thing” is?
Well, you take a vote. :-)
