The GOP has released a story about some magically increase in the # of pukes after the RNC. Ignore it. They think this because of the polls from Gallup, Newsweek, and others that show more people ID as repubs.
This same kind of thing happened back in 2000. Several pollsters (including rasmussen and gallup) got more republican respondants than dem ones and felt it would be the trend for the election (and so their left their samples unweighted). Why they got more republican respondants, i dunno. But these polls are usually done with small samples (700-1000) and are done in 2 or 3 days. The pollsters that used unweighted polls were either inaccurate or had wild, unexplained swings within a few days. Party ID seem to be a much broader issue to figure out and can't be pinned with quickie polls.
Pew Research, however, does seperate polls on this one issue with samples of around
20,000 and has shown that we lead party affilation in 2004 (33%-29%). With leaners, the numbers are 47-41.

These new quickie, unweighted election polls would have you believing that the RNC caused a
5% or more bounce in rupuke party ID.
here's a good read on that:
