And somehow Harold Ickes has all this blackmail power huh?  He must have been like Hoover, storing up data on everyone.

C'mon, conspiracy theories are ridiculous.  Sometimes the simplest explanation is the easiest one, and that is that the party leaders are torn on this as well.  I don't think any Democratic leader wants to anger one block or another.  I mean, there's a good risk that blue collar/rural votes, votes that should be with us, might be more in play than one would think with Obama than HRC.  Similarly, if it's HRC vs. Obama, there's the argued risk that the youth and African American vote will leave.

As for Richardson, I think it was an intriguing choice, although relative to making the decision come any quicker, I doubt it.  Are superdelegates going to come out en masse before Pennsylvania, and risk making themselves look foolish if HRC wins big?  Doubtful.  

If superdelegates come out, I expect it to be post-Pennsylvania, although personally, at this point, I think the best bet is that everyone is going to wait for post-Puerto Rico.
