The 45.9% of New Jersey that identifies as "White Catholic" includes many CINOs who support abortion rights and will vote for Kerry.
I agree the CINO's will not hurt Kerry's chances in New Jersey, but it could definitely hurt him in the Upper Midwest, especially in Wisconsin where his "Lambert" Field remark did not help him either. Outside of the shrinking city of Milwaukee and the SF of the Midwest in Madison, the rest of the state and Milwaukee suburbs are Bush country.
