Personally, I think that is is a mistake to look at this decline as some sort of confirmation of one party or another. If you really have to put it into part terms, I'd say that the closest thing we have is a general dissatisfaction with the two part system as a whole, although that conclusion is almost certainly too far reaching. Really, though, I just think that there is a general dissatisfaction with the way things are being handled, and people are a bit dissapointed that the Democratic victories in the last election hasn't seemed to change much at the moment.
