The first presidential debate between Hillary Clinton and Donald Trump promises to be the most watched ever, the audience could exceed 100 million people. A debate with an audience that size would be something never seen before in U.S. politics and would be a figure close to what the Super Bowl gets. The figure would be even more remarkable in an era in which Americans have countless cable and streaming options. These numbers are expected because we have already witnessed one of the most dramatic, volatile and unpredictable presidential races in U.S. history.
