Kudos to the interactive diagrams, but this seems misinformed about spoiler history.
The most famous "spoiler" was Perot, not Nader. Bush v. Gore was an extremely tight election, but there were third parties that drew more votes from Bush than Gore, and wer within the margin of error, possibly counterbalancing Nader's effect. Whereas with Perot, he received 19% of the popular vote, most of which were clearly drawn from George Bush, ensuring a Clinton win.
