2016: 19. Was generally disappointed with the rise of Trump, but didn't really feel like I could support Hillary to defeat him. I voted for Kasich in the primary (mostly because I vote in Ohio, where he was the only serious choice; I was nationally for Cruz through most of the primaries after Rubio exited the race), and supported Johnson in the general.
2020: 23. Still generally see the Republican party as a better fit for my values than the Democrats, but still have quite little faith in DJT. Voted for Weld in the primary (since Biden had already won the Democratic nomination by that time), and I intend to vote Jorgensen in the general.
This voting record paints me as rather substantially more moderate than I actually am.
Not to start this conversation, but if you want the party to return to its pre-Trump state, the best thing you can do is be part of an
overwhelming rebuke of Trump. He needs to lose in a landslide for the GOP to finally be forced to purge his QAnon-type base from the party. And that means voting for Biden.
Think about it this way -- on election night, are you going to be watching the numbers and hoping Biden beats Trump by as many votes as possible? Or are you going to prioritize hoping for Jorgensen to get 1% or whatever her goal is?
