I doubt that Giuliani can win in California, but he might force his Democratic challenger to spend resources there. That would be nice.
More than resources, If California becomes the battle ground, Hillary is going to have to say some really bizarre lefty stuff to get the vote. Can you say making campaign commercials for the Republicans?
We want to play on the RATS field and make them defend blue states with a GOP candidate with enormous cross-over appeal to independents and moderates.
Giuliani, in my estimation, is the best to offer so far.
