Now that former Pennsylvania congressman Joe Sestak has entered the race, there are now 24 Democratic candidates for the presidency (excluding Mike Gravel, who’s not running to win). That’s right – one candidate for every can of beer in a case. Or every hour in a day. Or both. Mercifully, all 24 won’t be onstage for the party’s first official debates, but there are nevertheless so many contenders who met the criteria for participation that the event has been split up into two nights.
