I think in my country that’s called “Stemmespild”
which basically means wasted-vote.
if a political party wants to enter the parliament, they gotta get at least 2% of the votes. so if you vote for one of the very unpopular parties and they only get ~1.5% you’ve effectively wasted your vote completely (This is how it works in my country - of course things are different in the US)
Trump is leading the polls.
so if you currently think “im not gonna vote”, then you’re giving trump a head start
A majority of the non-voters are more likely to vote for the democrats. thats also why the republicans are making it as difficult as possible to vote. coz they know, the more who vote, the less likely they are at winning
