Actually you can. based on the three most previous elections OH is 3-4 point more GOP than the nation. IA and WI about equal to the national average. CA, IL are about6 point more DEM, PA and MI about 3 points more DEM. Sometimes you get an outlier like NJ this time or IA in 1988, but you can predict a states polling average accurately using national polls.
my goodness you do like to spout your drivel, don't you???
