The overthrow of the American political system gat a great start from slick willy and government post placed purely by political bias got a immense start by slick will and pushed ever since. Polluting our law enforcement agencies, security agencies, government institutions like IRS, and postal services.
As that has been done for decades, look at how corrupt our government has gotten and openly criminal by politicians, yes i mean democrats. Our government now often sides with our global enemies and foreign Countries at war with us. Our secrets, weapons and even uranium sold to our enemies, our Treasury given to foreigners while many of our citizens live on the streets.
