The problem is, they are more than just "moderates". Look back about 5 years and you find all the major donors used to be registered other than Republican and were donating to Gore, et al. Folino is just one example. Burkle is another. Warren Hellman, another. The list goes on and on.
The Republican Party in California has been infiltrated by big-money "moderates" (i.e. ex-Democrats) who do not share the most basic principles of the party.
They lost their own party to the communists and now want to make the GOP their new home and jettison everything it has traditionally stood for.
