Maybe from the fact that the bloodless US political class has delivered nothing to ordinary people for decades, and people were ready to grab onto anyone who actually seemed to offer a promise of something different? Maybe from the vast swathes of racism that still suffuse the population, which aren't readily cleansed from a country literally built on white supremacy?

You libs love to use "sure the US is bad too" as a throwaway line, but you clearly don't actually believe it, seeing as you can't even imagine that this country could elect Trump without being induced to do it by Evil Russians.
