If you're a Mad Men addict like I am, you know that the Nixon/Kennedy race in 1960 was supposed to be no contest. Nixon was the favorite. Kennedy was considered too young and inexperienced for thinking voters to take seriously. But then, television changed everything. 48 years ago today, 70 million US viewers tuned in to see candidates debate issues on screen for the first time. Polls showed that people who watched the debate on TV thought Kennedy won; those who listened to it on the radio declared Nixon did. Politics was never the same after that.
