Howard Dean is running some kind of operation over there. You've got a Democratic primary that's tearing the party apart because he can't get a handle on the superdelegates, you've got two key swing-states disenfranchised by a party that whines endlessly about disenfranchised voters, and now this:
Puerto Rico's original plan called for selecting delegates at caucuses June 7. However, after the DNC approved the plan in December, it was discovered that the date was typo and should have read June 1, DNC officials said.
So the territory is switching to a primary and moving the date back to June 1. Is it really possible that nobody noticed a typo on the primary calendar for three months? Why not.
