I think there are basically three types of Super Delegates that should be tracked (at the state-level anyways).
1) Those who have SD status because they currently hold office (House members, Governors and Senators)
2) Those who have SD status because of a public office that they previously held (Speaker of the House, etc.)
3) Party officials
I think we need to track the type of SD on the table.
So this would mean reservering the SEO indicator for SDs who currently hold office.
Somebody like Al Gore or Tom Foley should be indicated by something else, I think. Off the top of my head I am thinking LEG for (legacy), but let's talk about it.
