Surprising lack of one-term Presidents?

Small sample size. Can't say anything meaningful. Though it is interesting that we're rounding ot the first  consecutive trio of two termers since Jefferson, Madison, and Monroe. Although if you give Truman FDR's last term, which he was the prez during most of, you have FDR (3), Truman (2) and Ike (2).

Historical coincidence, really. And I wouldn't say this until Obama's comfortably left office in January 2017; God forbid, but not counting Obama himself, 20.9% of Presidents have died in office of resigned. That's a very non-negligible amount.

Fortunately, medical care and basic hygiene have come a long way since we started having Presidents. And so have security measures. And Obama's only 51. I'd give his odds of surviving his presidency at much better than 79%. Is there an actuary in the house?
