The new house DPST members are all vocal about "Impeach the M...F,,,er". I have yet to see any of that ilk propose a legitimate charge for impeachment consistent with "high crimes, felonies, and misdemeanors."
Seems a charge of conduct upon which to base a charge of Impeachment is irrelevant to the DPSY's - It is simply Hate Trump - so Impeach.
Pelosi is quoted as going slow on the impeachment - perhaps Mueller will come up with conduct warranting Impeachment - although the House can define that as the majority chooses.
I suggest the House take care: Impeachment vote on frivolous - "I hate Trump" charges set a very poor precedent for the future of our representative democracy. It will come back to hurt the Nation.
On the other hand, if Trump is impeached for appropriate impeachable charges, and is convicted in the Senate by a 2/3 vote, I see the DPST assumption ini the liberal media that Hillar will be the successor. Some propose Pelosi as POTUS. Liberal DPST's and their faithful MSM have forgotten the 25th amendment. Pence assumes the Presidency, and nominates a new VP which requires confirmation of simple majority in House and Senate. I can see the Pelosi -led House refusing to confirm any nominee. On the grounds that the nominee is Republican nominated. That puts Pelosi next in line for POTUS.
Could Plosi engineer removal from office of Pence as well? She has thought about it, to be sure.
There is a saying- "Be careful what you wish for, You might get it". I personally have much regard for Pence than Trump. The DPST might find themselves with a canny political POTUS able to take advantage of their blind spots. If he survives Pelosi - and I would not want to be the heartbeat between either Hillary or Pelosi and the Presidency. Both of them are capable of anything they feel they can get away with, and Hillary has a long-standing protection bias with the FBI and DOJ - Pelosi would as well.
Let Mueller present what he can - let the House DPST vote Impeachment, there is only so much the DPST's can get away with at this moment. And, NO- Hillary won't be POTUS if Trump is impeached - regardless of the Putin- oriented left-wing MSM yowlings.
