At the Iowa county conventions today, as a result of Edwards and other candidate delegates switching their support, Sen. Obama picked up six additional delegates on Clinton (or, to be more exact, 7 to her 1.) “Edwards dropped 8 delegates to 6. Those six will be up for grabs, perhaps, at the Iowa Democratic Party state convention in June.” Update: Reports emerge that Obama’s Iowa take today could be seven delegates, or even as many as nine. That’s an Ohio-sized haul. Update 2: We’re going to need a bigger boat: Now, it’s Obama +10. Update: Also, +3 in California.
