Demonrats are unimpeachable unless Republicans hold 2/3 majority seats in both houses of congress.
A demonrat will never vote to impeach one of their own.
Owebama could don a Nazi uniform and eat an Israeli child on the white house lawn, and you still couldn’t get enough demonrats to vote to impeach him.
Blaming Republicans for that isn’t logical.
Do you think that Republicans would absolutely do so if they had the votes?
