Two more questions:
1. Why does texas have a ballot vote (primary) and a caucus (public voting???)?
2. What's the path to the democratic nom being confirmed? (e.g. how many primaries are left, what's the idiot's quick guide to these 'superdelegates')
Apparently they call it the "Texas two-step" in Texas. One of the guys who helped create it explains it.
For the super-delegates a bunch of people have gotten together to track them using MediaWiki. Their site is at superdelegates.org and it looks like their research will matter more and more since neither candidate has a realistic possibility of getting the correct number of pledged delegates.
