Much has been made about Hillary Clinton’s comment as to the differences between primary and caucus delegates. Josh Marshall has an analysis that shows this is not a meaningless distinction.
Specifically, caucus goers do not select delegates. They select representatives who go to the next level, either county or state wide, and at the end of this process, a delegate is selected.
So, if Obama representatives do not show up at these meetings, it is possible, and completely within the rules, for Clinton representatives to pick up some delegates this way.
Of course, we have Obama supporters whining that it’s not fair, but given that he raised $55 million dollars in February, investing a million or so in making sure that their representatives actually show up to the higher level caucuses would be a good idea.
