6. Duke vs. Edwards
David Duke, the former Ku Klux Klan leader and self-proclaimed fanatic, became a controversial figure for the Republican Party when he ran for Louisiana's governor in 1991. With nearly 500,000 votes, Duke declared himself the 'Republican candidate,' despite the party leaders distancing themselves from him. President George H.W. Bush labeled him a charlatan and a fascist unfit for any national office. Nevertheless, Duke had supporters and was allowed to debate Edwin W. Edwards, a three-term Louisiana governor. Although Edwards was a Democrat, he enjoyed significantly more backing from Republicans and the business community compared to Duke.
During their debate in a Baton Rouge hotel, the candidates were advised to avoid personal attacks. Duke targeted Edwards with corruption allegations and claims of nepotism, insinuating that Edwards had sold government jobs and pardoned his former boss. In response, Edwards warned that electing Duke would harm Louisiana's economy, potentially costing the state 45,000 jobs and $1.8 billion in recovery funds. The debates helped Edwards win over voters who supported Republican Governor Buddy Roemer, who had been ousted after finishing third in the primary. Edwards decisively defeated Duke in the election, securing 61% of the vote. Duke, however, declared a 'moral victory,' citing the majority of white voters who supported him. Some argued that Duke's success was due to the state's relative-majority voting system, and that Roemer could have beaten both Edwards and Duke had he entered the race.

10. Buckley vs. Vidal
The 1968 debate between left-wing writer Gore Vidal and the conservative firebrand William F. Buckley Jr. is remembered as a fiery and theatrical exchange. Set against a backdrop of social upheaval and intense political divide, the 10 debates between the Republican and Democratic parties culminated in this heated encounter in Chicago, a pivotal moment in American political television. Vidal and Buckley made no effort to conceal their mutual disdain. Vidal attempted to taunt Buckley by accusing him of being the inspiration for the transgender character Myra Breckinridge. Buckley, in turn, mocked Vidal's failed screenplay and relayed a message from Robert F. Kennedy suggesting that Vidal be sent to Vietnam. The debate escalated when the discussion turned to police brutality against protesters. Buckley argued that these protesters, by chanting offensive slogans and supporting the Viet Cong, were asking for trouble.
Moderator Howard K. Smith asked Vidal, 'Is it provocative to display a Viet Cong flag in a park, as we just saw? If so... wouldn't displaying a Nazi flag during WWII have the same consequences?' Vidal replied that while he supported Americans' right to protest, he believed the Viet Cong had every right to govern their country as they saw fit. Buckley countered by mentioning that many Americans had supported Nazi Germany during WWII, only to be condemned for it later. Vidal coldly retorted, 'The only Nazi sympathizer I can think of is you.' Furious, Buckley lunged forward and yelled, 'Listen here, you creep, don't you dare accuse me of supporting the Nazis, or I'll flatten your face.' Buckley later regretted losing his temper, having fallen into Vidal's trap. While the debate shocked audiences at the time, it also added a layer of humor, transforming a typically stiff political debate into an unforgettable television spectacle.
