And what did Marx think about voting for the lesser evil:

Even where there is no prospect of achieving their election the workers must put up their own candidates to preserve their independence, to gauge their own strength and to bring their revolutionary position and party standpoint to public attention. They must not be led astray by the empty phrases of the democrats, who will maintain that the workers’ candidates will split the democratic party and offer the forces of reaction the chance of victory. All such talk means, in the final analysis, that the proletariat is to be swindled. The progress which the proletarian party will make by operating independently in this way is infinitely more important than the disadvantages resulting from the presence of a few reactionaries in the representative body.

Karl Marx and Frederick Engels Address of the Central Committee to the Communist League, London, March 1850

The fact that those are your choices should be enough to alert you to the reality - that voting is a charade to make you feel "heard" and to keep you from turning on your overlords, who will continue to wage war for profit (be it on Palestine or on their own poor and marginalised) no matter what.

Sadly the propaganda is so strong that most people can't see beyond the pretend field laid out in front of them and the "blue vs red" mentality that is enforced along with it, so focused on this artificial division that they don't see that the real "teams" are society and those who exploit it for profit and power (and who control the media and the education system, ensuring you're indoctrinated this way from birth).

By all means, vote for the lesser (but still) evil (I'm in the UK, we are able to vote "none" which I will be doing if there is no one on the ballot who represents me), but you don't get to pat yourself on the back for it as if you've just stormed the beach on D day and singlehandedly defeated fascism, because that's nowhere near the truth, which is that you've just participated in a bit of theatre where you were given an illusion of choice. You being uncomfortable doesn't change that.
It could change you, if you decide to engage the discomfort instead of ignoring it, you can start here:
