Don’t have to be. It’s a 100% political act.
Dems have to go for it. They have nothing else and the truth is that that party’s constituent parts hate each other and this is the only thing that is left to unite them, “Russia collusion” having cleared the field of all alternatives.
I believe that the Dems are having a difficult time "uniting" the different constituent parts of their party. I am not sure if blacks are receptive to impeaching President Trump. I would bet that a majority of blacks don't want impeachment, and that is the problem.
The hard core leftists want President Trump gone, not just impeached. President Trump is destroying Obama's legacy. He's destroying globalism and he is showing that conservatism works.
The blacks don't want impeachment. President Trump is doing great things for the black community...lowest black unemployment in history, etc.
That is why the Dem black leadership is pushing impeachment...trying to move the needle in the black community.
IMHO
