Most political scientists say presidential debates don’t matter as much as we think they do in terms of their ability to change the outcome of the race. But history is rife with face-offs that allegedly decided elections: The debate between John Kennedy and Richard Nixon in 1960. And Ronald Reagan’s famous ‘there you go again’ line in his clash with President Jimmy Carter in 1980. And one week from today, Hillary Clinton and Donald Trump will take the stage in what many are predicting will be the most-watched debate ever. Guest host Michel Martin and a panel of guests discuss the first presidential debate, the issues likely to be discussed and what it could mean for the dynamics of the race for the White House. And we’ll also hear from Libertarian Party nominee Gary Johnson and Green Party nominee Jill Stein on being left out of the upcoming debate.
