Reid Wilson has the details of the brewing battle between DNC Chair Howard Dean and the McCain campaign:

Until the FEC reestablishes a quorum, after the standoff between Harry Reid and Mitch McConnell ends, McCain appears trapped in the system, but the agency cannot punish him. After they return, thanks to the complicated issues raised by the requests and complaints, it is likely the matter will wind up in court. A problem the McCain camp needs to prepare for: How will it look when the candidate who is most seen as a crusader for campaign finance reform is battling the FEC in court?

It's an interesting problem for campaign-finance lawyers to hash over. But perhaps an underlying lesson for McCain is that complicating the campaign-finance system does not make it better.
