Correct. The July 20, 1787, comments by Virginia delegate James Madison―later the fourth president of the United States―concisely summarize the rationale that resulted in the impeachment clauses which ultimately were adopted by the U.S. constitutional convention:
There are other aspects of the impeachment provisions in the constitution that are arguable, but the determination by the convention delegates to create a short-circuit mechanism between elections to remove an executive who abused his power really is not open to reasonable dispute.
Much of what you quoted that falls around actions that are not illegal acts are disputable, which is why a 2/3s majority vote is needed. This brings it to beyond dispute.
Anyway, perhaps with your much more esteemed experience in USA law then Bart can tell us exactly how Trump is manipulating the election, since, you know, you quoted that portion of his statement.
As an aside, I was watching a recap of Brexit and the Trump election that pretty much stated the intense dislike in each case was the direct result of elitists loosing for the first time. Elitists had the first election in a very long time where the outcome was not something they foresaw nor could handle. So they made a simplistic excuse for why it happened, focusing on racism and other misguided thoughts, and then tried to undo the election. This then lead to the recent landslide victory in Britain for the conservative party, and will more then likely lead to the re-election of Trump. Cant say I disagree.
Personally I welcome a complete landslide for both Trump and the republicans. It is beyond obvious the Dems in this country still wont listen to the average person (just look at their out of touch proposals like medicare for all), and feel an abject defeat is the only way to get the Dems to start listening again. Maybe after that we will have a healthy system of two parties pay attention to the center of the country, instead of only one with the other listening to the far left.
