I agree with you, but it would not have been within the margin of fuckery that allowed Florida to happen had Nader not be on the ballot. Gore did run a shit campaign though, all he really had to do was ask people if they were better off than they were in 92 and promise a continuation of the core of the Clinton policies and he would have won. Instead, he focused on distancing himself from a still very popular president and not being charismatic and largely allowed himself to be put in the position he ended up in.
It was my first election as an adult, Nader came to my college and gave his “both parties are the same” speech and I bought it because I was a dumb ass at the time and in fairness it was a lot closer to the truth then than it has been since.
