Which is odd, since there are 43 of them... (presumably they only put Cleveland in there once, but that still leaves us 42 + Obama). I wonder who got ditched?

Hard to say with precision—they cleverly dropped one from the period where they all look kind of the same—but I think it's Calvin Coolidge who got dumped (you can look at the pictures on Wikipedia (http://en.wikipedia.org/wiki/Presidents_of_the_United_States) and draw your own conclusions: Coolidge should be between the end of the fourth row and the beginning of the fifth). Somewhat appropriate, that we don't hear anything from Silent Cal... <grin>
