@FransVeldman @reay @cpr320 @ZoidbergForPresident @benroyce @ProPublica Voters aren't supposed to understand all the important issues. They're supposed to have a decent-enough idea of which candidate represents their interests best. And indeed, they do. It's incredibly hard, not impossible (nothing is ever impossible), but incredibly hard, to convince over half the population that their interests are something other than what they actually are.
Moreover, intelligent people aren't any less susceptible to manipulation than unintelligent people. Reducing the number of voters only reduces the number of people propagandists have to deceive to put bad people in power. Making it so that only "smart" people can vote makes that easier, not harder.
The current form of democracy is failing miserably not because stupid people are allowed to vote, but because the state is still a weapon of class warfare wielded by the bourgeoisie. No matter what the general population tries to use the state for, no change can actually be made unless the bourgeoisie allows it. Look at what ICE is doing now. The capitalists running the show demanded an unaccountable terrorist paramilitary, so they got it, and no amount of court orders or pointing at the constitution can save any significant amount of their victims.
The solution is to abolish the class dictatorship. To make it so that people with money and property can't unilaterally impose their will on us. Exactly how we do that, I admit I don't know. But that's the solution.
