As the public waits for post-debate polls to roll in, it’s important to keep in mind a key lesson from the 2016 U.S. presidential race: winning a debate doesn’t necessarily mean winning the election. In 2016, Democratic candidate Hillary Clinton was declared the clear winner of all three debates, with polls showing significant margins in her favor each time. However, as history unfolded, these debate victories didn’t translate into an election win.
After the first debate, a CNN poll showed Clinton ahead with a commanding 62% to Donald Trump’s 27%. Similar results followed across other polls like PPP (51% to 40%) and YouGov (57% to 30%). As the debates continued, Clinton maintained her edge. For example, after the second debate, CNN still placed her ahead at 57% to 35%, with Reuters, Fox News, and Politico echoing similar outcomes. By the third debate, Clinton was again deemed the winner, with polls like ABC showing her ahead by a margin of 52% to 29%.
Yet, despite this strong debate performance, the 2016 election results tell a different story. Donald Trump, though consistently perceived as having "lost" each debate, ultimately secured victory in the electoral college.
The takeaway from 2016 is clear: while debate polls capture public perception in the moment, they don’t always reflect the broader dynamics of an election. Factors like voter turnout, key swing states, and the electoral system itself play a far more significant role. So, as we look to current and future elections, debate "winners" should not be considered an automatic predictor of who will emerge victorious on election day.
