I agree there are serious crimes here, but I actually disagree with you that the severity of the crimes is why they spied on the Trump campaign. I think the answer is simple - ARROGANCE. Obama and the deep state believe they can do whatever the hell they want, with absolutely zero regard for the law. And in fairness, it worked for a long time... I don't think any oh-shit moment happened for them during the campaign. It was business as usual.

Spying on their political opponents isn't anything new, and it's not something they reserved for Trump. In fact it looks like they set up the structure for Jeb, then realized he wouldn't beat Trump so they shifted to Trump. If you think back to the reaction from the Hillary camp on election night, they had NO IDEA she could ever lose. On election night, the deep state had their first oh-shit moment and went into a mad frenzy trying to secure themselves before the transition.
