I think either way, Americans will do nothing. You could have impeached Obama, you didn't and won't rise up.
That being said, everyone, even the left hates Hitlery, while Chump has rabid fanatical supporters that will claim he will learn by his second term, in the impossible situation of him winning.
It is irrelevant what you do, but logically there is more opposition to Hitlery, and less fanatical support, so it would be easier to impeach her, even though it's very obvious it won't happen.
