I think you don’t understand how broken American democracy is. I would suggest you look into Princeton’s study on Democracy, the largest ever study of electoral inputs and outcomes.

Their results are rather shocking, including one of the most haunting charts I have ever seen:

This gigantic, years-long study shows that if 10% of Americans support a bill it has a 30% chance to pass, and if 90% of Americans support a bill, it still has that same 30% chance to pass.

Tldr: the opinion of the voters in America have no influence on its government. Votes don’t matter, only money counts. Your civic duties go much further than a mere vote.
