In 2016, you may recall since we had the discussion, I stated that I would NEVER vote for Hillary Clinton but that I did not feel Trump to be qualified for the office. Hence I voted for neither. (I do always exercise my right to vote and wrote in my choice.)
Amazingly, in 2020, I am faced with the same prospect and am quite disgusted by it. When a crisis actually befell the country, Trump performed as I suspected he would. He is not up to the task and prefers to wish things away instead of properly dealing with them. His communication and messaging is simply bizarre. However, I do not consider Biden at his current age and in his current state to be fit for the office in the least. I fully believe that Harris will be president in 2 years, give or take. I have no desire to vote for that either.
I personally do not believe in voting for the "the lesser of two evils" in the case where both choices fall below a minimum threshold.
"Hey, Biden is better than Sanders anyway" doesn't float my boat in the least.
