The point being that Gore was a crap candidate who ran a crap campaign, picked a crap running mate and lost votes all over the place to an idiot (admittedly, only with the help of said idiot’s brother and the supreme court).
It wasn’t the fault of Green party voters that he lost. It was his fault. And if Clinton loses (spoiler: she won’t) it’ll be her fault too.
The amusing parallel is that in 2000, while Gore ran a campaign as if embarrassed by being Bill Clinton’s VP, Hillary was getting elected to the Senate.
