I don’t exactly know what possessed me to dive into the polling blogs. They’re filled with dense, complex number crunching, analysis & very little humor. Dry is an understatement.

These changes are important for polling methodology and also present a politically important shift in the partisan balance.
I’m thinking that the statistical evidence of voters moving away from the Republican Party and into no party land is not a fluke, but indicates a problematic trend for the Republicans, particularly since the Democrats have not realized the same level of party identification decline.
Anytime you see a statistically significant change in a set of variables, you should think real change. This is not some sort of quirk in the numbers that can be explained away by attacking the methodology, although political spinners might find it useful to just chew up the methods and hope the GOP can turn this party id problem around…quickly. The real question is why a shift out of the GOP and not the Democrats and are these potential voters going to come back to the party at some time down the road, preferably in the next six months.
