Assume women go for Kerry 55-45, and men 45-55 (given history). A 60/40 split should have Kerry up close to 20%. 1-4% is just too low for battleground states if the sample is so skewed.
I cannot remember but seems like Bush was doing better than Kerry with women, more like 47/53 and Bush was marginall better with men. Anyhow, Drudge did a bad thing.
