Not much to add to the volumes written about the election, and which will be, ad nauseam. Biggest surprise since 1948, maybe bigger than that. Trouble is, Trump is no Truman. No one knows what he’ll be in office. So it’s an awful gamble.

Best not to dwell on it too much at this juncture. Instead, hum something cheerful.

Presidential facts to mull over. Assuming President Obama finishes his term, and it’s a safe assumption, it will mark only the second time that three presidents in a row have held office for eight years each. The first time was long ago: Jefferson-Madison-Monroe. Four times in a row has never happened.

Also assuming Obama survives his term — and all of the other ex-presidents do, too — then there will be five living former presidents for a time after Jan. 20, 2017 (Carter, Bush, Clinton, Bush, Obama). That’s only happened three times: March 4, 1861-Jan 18, 1862; Jan. 20, 1993-April 22, 1994; and Jan. 20, 2001-June 5, 2004.

Donald Trump will be the first president from New York City since TR, though of course FDR was from New York state and so were a number of others. In fact, with the upcoming addition, that will make six presidents from New York state, same as Ohio, “Mother of Presidents.”
