why do people vote in the us national election?

i dont get why people vote in national elections specifically? there is no right or left, only top and bottom. us chumps are not the top.

your vote doesn't choose anything, the electoral college vote does. you are giving your energy uselessly toward two clearly and purposefully apposed sides. completely polorized on every issue, and these people in charge could not give a single shit about you. ive seen more believable acting and story lines on wwe. 🤷‍♀️
