The occupant of the White House is extremely dangerous. He needs to be arrested for treason and kept confined and it should be immediate. Congress and state legislatures can, like S Dakota declare an opinion the he should be removed from office. Recall how it happened with Nixon. He was forced to resign.
Except you are forgetting one difference. Many republicans joined in the threat of impeachment for president Nixon. I have not heard of any democrats wishing to impeach Obummer.
Republicans are much more divided than the Rats. That is why we are forced to endure 8 years of Obummer.
