Republicans are happy because they've gotten one of their own into the White House... but he isn't a Republican, all he did was wear that mask. Sure, he may throw them a small bone now and then, but mostly he's going to try and be a strong president so he's going to strong arm them into giving in to his agenda, which I suspect is fairly non-existent. I mean, his entire campaign was based on lies, false promises, and Hillary hate.
From what I understand, it was those rural voters from the rust-belts of Pennsylvania and Ohio which put him over the top. I'm sure they're all happy as pigs in shit right now. I wonder how happy they'll be when their children get sent off to a war their President got us into because he's stupid.
They next four years are going to be a mess. I remember reading a comment by one of the Koch brothers in which he said they weren't going to get involved in this year's presidential because it didn't make a difference who won. The real election will be 4 years from now when the country needs to elect a president who will be able to pick up the pieces.
The unthinkable has happened. All we can do is deal with it.
