Fun factoid of the day:

Of the 100 sitting senators, 16 have run for president. Since John F. Kennedy won the presidency in 1960, becoming only the second person elected from the Senate to the White House, 47 senators have unsuccessfully sought residence at 1600 Pennsylvania Avenue.

The first number is what surprised me. Sixteen current senators have run for president? I had to enlist TPM's walking encyclopedia of politics, Eric Kleefeld, to help me independently compile the list of 16.

I put the list on a separate page for those who want to test their skills without a cheat sheet.
