Given how close that election turned out to be, this smear campaign likely changed the presidency, and given George WMD Bush's actions, changed the course of the world for the worse in many ways. (For those who were too young or not yet born at the time, these jokes were MASSIVE to the extent that became largely Al Gore was known for, for years after. So it's not much of an exaggeration to say they had a material impact on his perception and hence the votes.)

Al Gore understood technology, the internet, was a champion for the environment, and it's unbelievable today that he came that close to presidency (and then lost). When people say "we live in the bad timeline", one of the closest good timelines is probably one where this election went differently.
