yes, that is true. but the issue is that more people tell pollsters that they're democrats ~ and that's what the pollsters work with.

Actually not completely true. Both Rassmussen poll on voter id and current state by state registration numbers do not show that old standard of "Democrat voter registration dominance" to be as universally true as it use to be. So pollsters who base their polls based wholly on self identification could just be reaching more Democrats.

Serious polling weights for a reasonable mix of D-R-I based on figures such as voter turn out, current voter registration and other factors rather then simply calling up and asking people which party they identify themselves with.

What you term "serious polling" also turns quickly into NON RANDOM SAMPLE POLLING.

If you really want that in a poll I can write one up now for every competitive voting situation in the country ~ $10 tops ~
