only if you're in a swing state. In which case vote tactically. If you're not in a swing state do not vote trump and do not vote Harris. Instead vote third party there to maybe get a 5% national representation and therefore get more funding for em.
Also if enough people in California, NY, etc. Vote third party they may deny Harris a popular vote win while still allowing her to win in EC. This would both send a message about ignoring the left and might make it so Republicans start supporting getting rid of the electoral college too.
If both of the parties had an election stolen from them in less then a decade due to this dumb antiquated system maybe they'll muster some political will to get rid of it.
