First of all, GOPers have to keep their trunks up. The party is not over. While sad and bad, this was no electoral disaster, no huge tragedy. Both parties have faced much bigger crisis in their histories, and survived.
I realise that, but take a look at the exit polls and compare them to 2008. Single women, and Jews both swung Republican somewhat, while Hispanics swung slightly towards Obama. If the Republicans are stuck at 30% of one of the fastest growing voter groups in the country, they are in major trouble.
