Those who have a say in America voted, and collectively they know what is best for America. They know who reflects what is best in America. Those who didn't vote either don't care either way and their voice doesn't matter, or they are minors and can't vote, or are felons and can't vote.
So among demographics, they know what's best for America (the majority vote) the rest don't matter. :)
Like many kids in life, they have responsible parents, good parents even. Those parents take the good with the bad and end up being a strong foundational support for the child that the child can turn to.
Not every family is dysfunctional :D
