2001?
Dude, it started long before that. One could argue that it was Newt Gingrich, and the Contract With America in 1994. Or the repeal of the Fairness Doctrine in 1987, which allowed unregulated propaganda. Or 1986, when Rush Limbaugh's show proliferated around America, quickly becomes the Conservatives most successful recruiter and indoctrinator. Or in 1974, when the Republicans took advantage of the post-Watergate chaos, and passed a new tax code that baked in Trickle Down Economics.
Personally, I maintain that it all started in 1968, when Bobby Kennedy was assassinated. He would have ended the Vietnam War earlier, saving thousands of lives, and taken America in a completely different direction. Instead, Nixon was elected, and took us down the path of evil that has led to us being occupied by treasonous, corrupt, pedophile MAGA Nazis.
