As if there is really a choice? The choice will likely boil down to voting for Biden, whether you think he's too old/too moderate, or if you think Kamala as a POTUS is something you don't think she's up to....who cares? The other option is basically supporting a fascist.
Lodging a "protest" vote is stupid and childish and you might as well vote for donnie if you are going to do that. And voting for donnie is voting for a person who hates democracy as well as this country.
If we ever get ranked-choice voting, things might be otherwise and you could lodge a protest vote then. Until then, there is too much on the line...
