To post what I just put in a reply...
If you want Biden to win, don't shame voters considering not voting, shame Biden and his administration to actually do things for his base and get them some human rights, and tell him to quit genociding Palestinians.
Use your energy like that. Like literally everytime you reply to some person thinking about not voting, instead write an email to your boy instead and tell him to do something that infers he actually wants to win this fucking election.
