Absolutely there's value to polls of registered voters. I have no problem at all with them. But that doesn't preclude anyone from comparing a registered voter poll sample to actual turnout in past elections, just because it isn't of likely voters. We compare/analyze what we're given.
I do think the poll oversamples Democrats, but not as much as you might think.
One thing to keep in mind is the difference between asking for Party ID and asking what party you are actually registered with
The 2004 and 2008 questions were strictly voter ID, this one was party registration Someone could be a registered Democrat, but identify more with being an Independent or even a Republican, and someone could be technically a registered Republican, but identify as an Independent or Democrat
You probably do see a fair amount of registered Democrats in the Panhandle of Florida, that might technically be registered as a Democrat, and may show up that way with a registered question, but if it was a party id question might not.
