Even as a bumbling idiot, he came dangerously close to creating a constitution crisis that he could have used to retain political power. Just a few key people had been swapped out with some loyalists and it could have easily become the case. A congress recognized this, which is why they acted so quickly in a bipartisan way after the election to put into law that the VP can't just pick whatever electors they want. Now he knows more and can demand more loyalty, so it is very brave of you to assume that this is some non-real risk. The system held, but it did show that it's not invincible.
It’s not democracy if you’re continually being forced to vote for someone who doesn’t represent the people over and over again with no end in sight.
The problem is, as I said in another post, that the solution to this problem is a ground up approach. Voting for a third party, even if that third party wins, solves nothing as it would just tend right back to a two party system again. It's the nature of the FPTP voting system. This needs to start at the bottom where you get people who will change local elections first, and then work up.
