Video | The keys and what to look for in a presidential debate

Televised debates have more than six decades of history in the United States and, on occasions, they have managed to change the course of electoral campaigns. The Democratic candidate to renew the presidency of the United States, Joe Biden, and his opponent, former Republican President Donald Trump, face each other this Thursday in the first of the two face-to-face meetings agreed on on their way to the polls on November 5 . The second is scheduled for September 10. In the video that heads this news, Alana Moceri, professor of International Relations at IE University, and Daniel Fernández de Miguel, associate professor of History at the Carlos III University of Madrid, explains how ideas and proposals are not the only things that spectators see on the night of the debate. Non-verbal language, the presence or absence of an audience and, in the most recent campaigns, the impact on social networks, are aspects that can define the winner of a debate.
