“Do third-party candidates — and their voters — affect elections? Yes… Remember that time 19% of Americans voted for Ross Perot?”
How did Perot affect America? What is different because of the votes he received?
The only thing I can think of is it might have made Bill Clinton president instead of giving George HW Bush a second term.
But that’s the exact thing you’re arguing against, so how did Perot affect anything besides potentially swinging the election from Bush to Clinton?
