Nothing that wasn't already known, and nothing that people of color (particularly Black people), have been saying about this country for generations. Only it will no longer be as hidden and downplayed as it's been the past 40 years.
While, yes, the voting system is busted, but what's more busted is the fact that our country is built on principals of slavery and oppression. It's baked into the DNA of this place. It permeates every facet of it, from governmental, to judicial, to social, to economical. A broken electoral system isn't the root, it's a symptom.
