I am missing something here. All the polls listed say that they sampled more Democrats than Republicans. But does this mean there are *actually* fewer voters identifying themselves as Republicans or only that all the polls are using biased samples?
Party ID, like most self chossen ID changes very slowly if at all. This "more people are telling us they are Democrats" rationalization of the floating sample school merely means they called more Democrats in that sample. It garbage. I suspect this new methodology is going to be completely discredited by this years election results. It is a seriosly flawed methodology since it does not control at all for the pollster simply getting more Democrats to respond. They should be using the tried and trued method of basing their sample on turn out for the last 2 elections.
