For arguments sake let'ss they bring the articles of impeachment. At that point you have what amounts to a trial and evidence will have to be presented. The only evidence they will have to present will be the Mueller report.
That is not accurate. An impeachment inquiry would give them more power and they would not have to limit their inquiries to a legislative purpose. If they need access to something the white house is blocking, an impeachment inquiry would be able to open the door for them.
There is not enough in the mall report to conclusively show that a crime was committed. That not was standing some strong left leading Democrats will vote yes for impeachment. another group of Democrats will see that there is no conclusive evidence and will not support it. Republicans will have a very small majority that would support it. The odds of it getting out of the house are slim. Like it or not the House and Senate are in essence a large jury and the vote will not be decided on the merit of the case but on the political ramifications.
True, but like I said... that goes with the acknowledgement that any president from here on is essentially allowed do what they want and obstruct any investigation into their behavior. I am not comfortable with that, and I am sure you will agree once a democrat is back in office.
