Presidential votes are different because the Electoral College. A third of my state's 2020 voters could abstain from voting Biden or vote 3rd party and Biden will still most likely win. So the calculus is way different than for say, congressional offices. Unless you're one of the say 100,000 or so people living in a swing district in a swing state your vote for president is probably already decided due to the Electoral college.

It would take a catastrophically unpopular policy stance to threaten the electoral college vote in my state, and the same is true for most US states.
