How we really chose presidents

Today's N.Y. Times op-ed page has a great graphic comparing the height and weight of presidential candidates.
Taller guys beat shorter guys by a 2-to-1 margin and heavier guys prevailed over lightweights with equal dominance. But I took the N.Y. Times analysis one step further and combined the two measures. In the 28 elections since 1896, the winner was either heavier or taller than the loser in all but three cases, thus proving beyond all doubt that Americans want the bigger guy when deciding who should run the free world. The most recent exception was Bush v. Gore; Al Gore is an inch taller W, but we all know he actually won the election, so there's an exception that proves the rule.
Harry Truman, a man of average stature, beat Thomas Dewey, who stood a full three inches over him. Likewise, Teddy Roosevelt was two inches shorter than Alton Parker when he won in 1904. But both men had reputations for their outsized personalities, so again, I say they're exceptions that prove the rule.
Where do these statistics leave our current candidates? Obama is 6' 1½" and 180 pounds. John McCain is 5' 7" and 165 pounds. There hasn't been a president as short as McCain in a hundred years. The closest weight was Calvin Coolidge, who was only four pounds heavier, but he was still three inches taller than McCain. Turn-of-the-century president William McKinley was 5' 7", which was the last time such a short man was president. And, well, he was shot to death in office.
Every president in the television age has been at least 6 feet tall (Well, Nixon was 5' 11½").
Who will win in November? You decide.
