Hill would rule by fiat or issue such a blizzard of executive orders that congress and the country would throw up its hands in defeat. Mandate, shamandate. Hill would claim anything she liked, and the MSM would parrot the lie to the rooftops.
If Congress rolls over for her when she doesn't have a mandate, then we'll know that there's no difference between Democrats and Republicans, and we should give up on them altogether. This is a good chance for Republicans to finally learn how to grow some backbone, because they sure as hell don't have any now. It needs to be sink-or-swim for them.
