A typo on Puerto Rico contest date

Just when you thought the Democratic presidential race couldn't get more bizarre, comes this.

For months, the campaigns and the Democratic National Committee -- not to mention the media -- have penciled June 7 on their calendars for the Puerto Rico caucuses as the last contest of the nomination campaign.

But now Roberto Prats, party chairman in the US territory, tells the Associated Press that the contest has actually been long scheduled for June 1 and attributed erroneous reports that list June 7 as the date to a typing mistake in a document sent to the national party.

Huh?

And, by the way, Prats said today, the state party central committee decided Thursday night to hold a primary instead of a caucus to encourage more voters to participate -- and just perhaps get Hillary Clinton and Barack Obama to campaign on the island.

Puerto Rico's primary, with a significant 55 delegates at stake, could end up being far from the end. Montana and South Dakota holds their primaries on June 3, and it's looking increasingly possible that Florida and Michigan could do do-overs in the following week.
