I don't really understand. Suppose democracy as we know it is dismantled and we have an autocratic supreme leader eternal... will it be helpful to "explain to people that those in power do not have popular support"
voting for lesser of two evils and voting for absolute support is also indistinguishable.
This is also a flawed premise, as though casting a vote is supposed to be an expression of your self and your personal desires on path to utopia... it's not. You're voting for which asshole you want to be POTUS. That's it. There is no lesser of two evils or tepid support or partial agreement. Do you want Chocolate, or do you want Strawberry.
