The New Republic reports that Michigan "plans to get out of its uncounted delegate problem by announcing a new caucus in the next few days."
Said the source: "They want to play. They know how to do caucuses. That was their plan all along, before they got cute with the primary."
"Michigan Democrats had originally planned on caucuses after the legally permissible Feb. 5 date, but then went along with top elected Democrats, including Gov. Jennifer Granholm, who pushed for an early primary."
a Michigan "caucus" is essentially a primary held by the party on a given date during shorter hours than a primary--probably 10:00 to 6:00--in a limited (but still significant) number of locations, where you essentially show up, declare in writing that you are a Democrat, are handed a ballot upon which you vote, drop your ballot in a box, and leave.
It's a caucus in name only.
