Elizabeth Warren, 70, was the youngest serious candidate in the Super Tuesday battle, and it certainly wasn’t any help. Coming in third in her home state was a terrible way to end a campaign. But when Americans in the future look back on her career, they’ll remember Warren as one of the pioneers who, like Hillary Clinton, helped to get the nation used to the idea that there’s nothing unusual about voting for a woman to be president.

Either Biden or Sanders, if elected, would be the oldest American entering a first presidential term. As of right now the record is held by Trump, who was 70, followed by Ronald Reagan, who was 69. Reagan went on to a second term that many people felt was marred by a certain … mental slippage. It’s sort of hard to tell whether Trump is failing in that way since he was so awful when he started out.

Well, we’ve had plenty of presidents who seemed to go off the rails in the prime of life. And these days an average man of 77 has about a 10-year life expectancy. That goes up if he doesn’t smoke or drink. And I’ll bet it really skyrockets if he has the entire staff of Walter Reed hospital at his beck and call.

The first time age was a big issue in a presidential election was back in 1840. William Henry Harrison, the Whig candidate, was 67 and his opponents referred to him as “a living mass of ruined matter.”

Harrison promptly released a doctor’s report: “vivacity and almost youthfulness of feelings. … Bodily vigor as good as that of most men his age. Subject to no disease but periodic headache.” For its time, it was probably more thorough than the one we got from Bernie Sanders.

Then, of course, Harrison got elected, went to Washington, and died a month after the inauguration. The only lesson the nation should derive from that story is that it’s a bad idea to give an extremely long inaugural speech in inclement weather.

Trump, who revels in his ability to attach insulting adjectives to people’s names, calls Sanders “Crazy Bernie.” That’s a tad ironic coming from a man who has been driving the nation nuts for more than three years.
