SurveyUSA seems strongly pro-Democrat this year in a lot of places.
In 1994 the polls were way off, but now pollsters know how to take election shenanigans into account. Every time I see a party breakdown, the pollsters have always polled more Republicans than Democrats, even in areas that have more Democrats.
I actually thought the Democrats would gain seats in 1994, based on the polls, but the polls didn't take a lot of things into account then that they do now (such as Republicans cheating).
Can you give an example or two of the partisan polling issues?
It's not that I disagree with you that the polling
could be wrong. It's that it usually isn't.
