Since 1960, the Democrats were the party that nominated new generation candidates. Three of them — Kennedy, Clinton and Obama — won the White House. Republicans nominated old guys, whether they lost — think Dole, McCain and Romney — or won, like Ronald Reagan. But this year, the geezers are on the Democratic side. Hillary Clinton is 67, Bernie Sanders is 74 and, if he gets in, Joe Biden is 72. On the Republican side, for a change, it's a completely different story.
