Here's the thing, as fucking awful as Trump is, I don't think this is a responsibility he's going to take lightly. I think what we're seeing is Trump realizing he doesn't know what the thought he knows. He's been so full of bluster but now is the time to put the rubber to the road and he can't just get what he wants. He knows congress is half with him, and the other half thinks he's the worst thing ever. He knows all the shit he said during his campaign will dog him and he's a guy who can't stand being criticized. So what did he do? He just put the biggest fucking target on his back that he could. The WHOLE WORLD is going to be taking shots now for 4 years, and this is a guy who has a ginormous ego.
The IDEA of being president probably excited the fuck out of him, but I think the actual job of being president is something that just grinds you down. Look at Obama. He looks 30 years older than he did when he took office. That's going to happen to Trump. And he knows it. I truly think he wanted it to be close but didn't want to be president because now he's responsible for more than just himself.
