That's my theory too, and US is not the only Western country where this seems to be happening. Voter turnout is falling across the whole Western world, and a big part of it is probably people realizing politics is a circus, and not wanting to touch it with a ten-foot pole. When every choice is equally bad, and you'll have to find your way around the problems by yourself anyway, what's the point of even caring about the political scene? Getting some laugh at its expense is about the best use one can find.
