Independent/3rd party candidacy

I’m curious what your thoughts are about my proposal here. I understand if you are wary of sortition, so for now just consider if electors were chosen by some proportional method instead:

I personally would rather that the average American focus on local politics than the president. I’m not saying the president is unimportant, but we’ve really gone overboard and spend a disproportionate amount of time talking about it. And Congress shouldn’t be delegating so much power to the president anyway; they should have a healthy level of caution towards him.
