As an outsider, watching Americans complain about political fatigue is fascinating, and informative. Very clearly there is a pervasive feeling that the political apparatus of America is ineffectual. But instead of seeking to become engaged, many are sucked in by media rhetoric that assigns blame to a menacing adversarial out-group.
> It's not pervasive corruption that's to blame, it's the evil culture of people not like you and their corrupt representatives!
We have this where I live, but thankfully we also enjoy a fair amount of mobility; it's less common to be entirely surrounded by those who vote the same as you, and most ridings have flipped between two or three parties over the coarse of most constituent's lifetimes. While the ethnic diversity of the ridings has generally increased over the same time.
Americans could use more political diversity; you're choosing between neocons and neoliberals, and fighting visciously against each other to do so.
