Don't fucking stop. Don't listen to the polls, good or bad. Our republic depends not merely on winning, but running up the score, so that there's no doubt about who won.
And if that's not enough reason, every vote for Kamala is just 1 more Psychic damage that Trump takes after the election. He thinks everyone loves him; your vote is proof that he's wrong, and it will drive him MAD.
Vote. Vote. VOTE.
That shouldn't be surprising, given his history.
