That's where the dems blew it in my opinion. When you have people saying, "impeach the MF", "Impeach 45" and, "today is the first day of impeachment, all before the man was sworn in, it's clear this isn't about justice or the constitution. This is about an outsider winning a race he was supposed to lose.
I also think Nancy was right to hold off as long as she did. Biden isn't even the nominee yet so nothing Trump found out about his background and his son's job, means anything yet.
The very interesting thing, as pointed out today, IF Biden is elected, he will immediately be brought up on impeachment charges for using his powers when he was VP to withhold aid to a foreign nation. Unlike Trump, he said it on tape. I hope they have a good running mate for Biden. He/she might become President.
