He didn't just "snap," like a couple reporters on Fox are speculating. He had to have planned this, you just don't bring that much ammo and that many weapons to a hotel room unless you have something in mind. And Fox News is reporting that he specifically asked for that particular room in the hotel. He has been planning this for a while.

He seems to have been an avid poker player and casino gambler. I don't know how that factors in.

I've been told there is a video of him at an anti-Trump rally. I haven't seen it, and I don't even know if it exists, but that is the only thing I've heard about his political leanings.

You can do a lot of damage with 30-round mags, if you have enough of them. And if he can afford that many weapons and that much ammo and that hotel room, he could afford the mags.
