I mean, to the extent any voter is “responsible” for what happens, if you abstain from voting or explicitly vote for a candidate you know is going to lose to make a point, then you have some responsibility for the result

The vote of a majority of people in the country will have no impact on the result of the election whatsoever. Most of us don’t live in the sliver of electorally competitive states.

If you live in Georgia, you should be deeply pondering the very real consequences of a protest vote, but this idea that every voter is responsible is just not how our system works.
