Either way, your vote is thrown away. Even if you live in a perennial swing state like Ohio, you're vanishingly unlikely to swing the election to the party that beats you with a velvet glove instead of iron knuckles. And if you don't live in one of those states, it's... even more vanishingly unlikely.
The issue with voting isn't that it influences the government one way or another: it doesn't, and pretty much any of us can get more influence by working all those hours we would otherwise think about politics and using that money to purchase connections with actual power brokers (though even that is mostly a waste).
The real issue with it is its influence on your identity. Electoral politics is a twisted parody of real politics, morphing autonomous values and communal choices into something closer to the emotions felt when watching team sports. My guy good, your guy good. Which isn't bad, in itself--it's a form of entertainment like any other. But it's not real politics.
My suggestion would be to skip voting for all federal offices and maybe even state offices, and focus on the local, if you must do electoral politics.
