I already voted in the United States election by paper ballot on 2020 October 5, the day I received it by mail.
My first choice for President & VP would have been Transhumanist Charlie Kam & Liz Parrish, but they were not on the ballot. I had already decided that if any candidate worthy of my vote is on the ballot, vote for them, fill in a little circle with black ink, because I do not trust the board of elections to count my vote if I write it in.
But, now I am slightly regretting for whom I DID vote - Green Party Howie Hawkins - because I just now discovered he pushes this distracting meaningless unfalsifiable Russiagate crap about Trump. Now, I know no candidate will be perfect, and Hawkins is no doubt MANY orders of magnitude better than most of the other candidates on the ballot.
However, elections are the one RARE instance a person has total control of whom they're picking, & I don't want to waste my vote on anyone OTHER than the BEST candidate for the job. But, if my vote won't be recorded at all if I write in, then that IS a logical reason to vote for a second-best - better than not getting one's vote counted at all - although even in that case I can still always tell everybody ELSE to vote for my first choice: if THEY feel they DO trust their election boards to count write-ins, or if my first choice is on the ballot in THEIR district.
