People "vote against their interests" is a notion that smacks of elitist snobbery and patriarchal disappointment, proclaiming a failure (blindness or idiocy) to perceive future benefits and overcome emotional/social pressures.
Yet our government permits gambling, lotteries, and alcohol—hardly beneficial to anyone, instead encouraging self-destructive tendencies. So, this reversal of occasionally demanding sober decisions is scarcely consistent.
Moreover, defining ‘best interest’ is tricky: Is it economic or familial values or pride in honest, hard work despite low pay?
America’s founding was based on rejecting taxes and religion. I’m sure the crown assumed the ‘best interests’ of English citizens were aligned with the monarch’s desires (such as a new wife, Henry VIII, or empire expansion and war, George II & III). After numerous cases of abuse, the wisdom of leaders and their promises to "care-take" are thinly veiled acquiescence to future abuses.
And yet, we must outsource our ‘best interests’ to representatives, who should moderate their ambitions/desires to interpret and act on behalf of a populace, some who struggle to envision a better life, but can still allot a portion of hope through a vote. To declare their vote foolish is to become foolish ourselves: to stop listening and play wise for our desires.
