The problem I have today is that I fundamentally disagree with both options and think we will be worse off with either one.
I am totally fine accepting and supporting a candidate that I generally agree with, or even just agree with on a few key policies. I'm not okay with having to pick between one candidate who I view to be a sociopathic narcisist or another who I view has being well on his way to serious cognitive issues. Assuming Harris is the new candidate, I'm now left with the narcisist and a candidate who I view as unfit for duty, and an ineffective candidate who fell into this position thanks to a combination of DEI and a white house that refused to accept the limitations of the president.
If, on the other hand, voter participation goes down noticeably it can drive change. Both parties will know they lost support and, more importantly for them, have voters to win over. It also opens the door for creating a real chance for a third party that doesn't exist when we all continue to accept the unofficial duopoly that started way back when Hamilton and Jefferson were tearing the union in two.
