Yes, you can still find moderate politicians if you look hard enough. They tend not to get the level of media attention of the extremists, but as they're inherently in "purple" districts, they tend not to have the political longevity of politicians in deep red or deep blue districts. More's the pity.

Most Republicans aren't deeply racist and most Democrats aren't deeply socialist. Americans largely want a functional representative democracy, with minimal restrictions on free markets and free speech and some measure of opportunity for all. Obviously "minimal" is subject to interpretation, but this is tinkering, not an absolute rejection of free speech or free markets or social justice.
We take these important fundamental values for granted as we pour political energy into disagreement over which bathrooms trans people should go to.
