Which third-party candidate won a significant portion of the popular vote in the 1992 election?

Ross Perot is the correct answer because he garnered nearly 19% of the popular vote in the 1992 presidential election. This was a remarkable achievement for a third-party candidate, especially considering the usual dominance of the two major political parties in the United States. Perot’s campaign focused on issues like reducing the national debt and reforming government, which resonated with a significant number of voters disillusioned with the existing political establishment. His ability to capture such a large share of the vote is notable in U.S. electoral history, as it demonstrated that third-party candidates can sometimes impact election outcomes and draw attention to specific issues.

The other candidates mentioned, while significant in their times, did not achieve a similar level of influence in the 1992 election context.
