He IS the coup.
I don’t think Obama as a leftist adheres to any serious principles which would make him view a coup as a terrible thing.
As for amnesty it only makes sense for him to do it after the election. Even a Republican Senate will not be able to remove him.
He may have toyed with doing it sooner to energize his base but the dems running for office told him to back off. Still he is flooding the country with illegals so who knows.
