I was specifically talking about Trump and his cronies and not the much broader in scope debate about the general corruption of others.But we're talking about political parties undermining democracy. The DNC making up treason against a sitting president should rate very high on that list.
Regarding the Ukraine that's actually a really interesting situation I've been reading more about lately. The average person knows very little of what happened there in 2014. Fun fact: The western governments backed some Nazis.
As to which leaders supported Nazis, I'm not sure how it's germane?
