Congress doesn't represent America in any way except our advertising ideals. Hell, they probably don't represent themselves.

They represent themselves the way everyone thinks they OUGHT to be. (this isn't an original idea with me, btw, I found confirmation in "Collective Illusions" by Todd Rose)

The vast majority of people are not especially Christian; but they think all their neighbors think they are, so they behave as if all their neighbors are more Christian than they are. They aren't especially racist, but they think all their neighbors are racist, so they behave more overtly racist than they might otherwise believe because they want to fit in more with the neighbors. And since all the neighbors are doing and thinking the same thing, it's an endless self-reinforcing spiral. Rose opens his book with an example of a really "Christian" church-driven community that was ultimately found to be driven by the attitude of a single, loud, hostile woman. She set the tone by making more noise than anyone else, and passive acceptance plus a desire to fit in kept everyone else in line.

Politics is just society in macrocosm. They pander to the loudest, noisiest elements because the assumption is that anyone else would say something if they didn't like it--right? So we must WANT "Christian" politicians who favor loose gun restrictions, harsh abortion laws, and close ties with Russia, because that's all they hear.

And don't bother telling me "o but we do tell them! all the time!" You do not. If people had the courage of the convictions I see online, DC would be a smoking ruin. We ALL want to fit in with society and not make waves and take the path of least resistance. The ones who are out there waving gunz and dead babies on pikes are the ones they hear.
