Well I will forgive your misunderstanding of our Constitution. It takes a 2/3 super majority in the Senate to convict, and the last time I checked the Republican still control the Senate.
The other issue is that judging him as the worst President of our era isn't a basis
for impeachment. Moreover, those afflicted with TDS can't even establish that.
They have strong feelings of hatred for Trump, & believe this makes him the worst.
But by objective criteria, they haven't made a case. Under his reign, we have no
wars started, no major terrorist attacks, no economic decline or malaise, a couple
decent USSC justice appointments. About the worst is that he hasn't repealed
Obamacare, & he hasn't controlled our southern border. I'm sure you can think
of other pluses & minuses.
On the whole, he's better than at least GW Bush. Of course, this could change.
