In theory. One would think that the American people would demand his head and that voting to keep him in office would be political suicide. The opposite is true now.
But this is why I've said over and over and over again that this is a personality cult. It's not blue v red, conservatives vs liberals, Reps vs Dems. It's pro-Trump vs anti-Trump.
The Framers never expected elected representatives to put party over country.
@blueinsa's point I think is that since this is where politics has now gotten to, impeachment itself is pointless. But that presumes that this is where politics will always be, or always has been. The latter is wrong for sure and I doubt the former will be either.
I'm not scrapping the Constitution because of this guy. This is why I will vote for whomever runs against him. And I voted for Romney.
