Abstain?
You're spending an awful lot of time on buyer's remorse. You're a good bro, but just admit this experiment was an abject failure.
I honestly don't see it as a failure, and I don't have buyer's remorse. If I could go back in time right now knowing everything I know now, I'd still cast the vote for Trump because of the two appointees to SCOTUS. That alone.
Doesn't mean I have to like the guy I voted for. I'd have disliked Hillary as well.
