I don't think that Kerry being Catholic will hurt his vote at all. If Lieberman can help garner 48% of the vote while Jews represent only about 6%, I seriously doubt that a Catholic population representing about 26% can't do as well. The difference is that Lieberman is a dedicated Jew, whereas Kerry is a wishy-washy Catholic. I'm one Catholic who will proudly vote for Bush.
Me being a Catholic doesn't affect my vote AT ALL!!! In fact I am itching to boot Santorum in 2006. In fact I would also vote Specter over Toomey if it were between them two in a primary. I'm starting to think there are NO moderate Catholics anymore! You either have to be a Mass. extreme liberal or a nut-job pro-life conservative.
