Seriously, now that you reminded me, I do recall that Rasmussen claims that his strongly approve/strongly disapprove polls are predictive of the general polls. Without having closely studied the data, my impression since the inauguration is that the strongly disapprove group has in fact predicted a growing group of those who generally disapprove.
I think you and I agree that they are predictive also of intensity. So we have movement in the right direction and we have intensity.
Now it is only a matter of predicting how the Republicans will screw this up.
Are you academically trained in statistics or polling? Or are you just a great writer?
