(I too am dismayed by the internet voting thing, but I'll still be participating nonetheless.)
Since you read the criteria, this could be a rehashing of sorts, but here's how the process will work, as I understand it:
It appears that in order to serve as a district delegate, you must file to be a delegate
after the caucus. Then at the district convention a few weeks later, participants will be divided into caucuses based on whom they support for President. Then, gathered in caucuses for each candidate, you will elect so many delegates as your candidate received in that district.
The Ninth has six delegates, three of whom will be women, so your odds are slightly greater than are mine in the Third as a male.
As for statewide at-large delegates, 17 are reserved for PLEOs, but the other 28 are open to all; both sets of at-large delegates will be elected by State Central in May.
It sure doesn't hurt that you were quite active on Skinner's campaign; maybe she can help you out. My advice: Solidify your rapport among Democrats in your area. Stay involved with your local party. This will definitely help in the event that this is a contested issue.
Some of the names of 2004 delegates sound familiar (
http://politicalgraveyard.com/parties/D/2004/MI.html), such as John Conyers, Tina Abbott, and Joel Ferguson, whom I believe were all unpledged delegates. Many of the names do not, so it's not like only party 'elites' will be going. Good news for both of us!
