I agree in our unalienable right to keep and bear arms, but I also support wait periods, background checks and forbidding the sale of machine guns. I am with you on "gun control" having become un-Constitutionally restrictive in many areas and believe every citizen should be allowed to own guns if they have no criminal record.
If Schwarzenegger does want to restrict gun ownership even further, can you tell me in what manner he proposes to do that? And as for how I can "support such a politician", I don't define Republicans by just a small selection of issues out of the hundreds addressed by the GOP platform. I also believe in long-term political strategy and conservatives consistently putting forward the MOST right-wing candidate that a given population is ready to elect. Whether we like it or not, the Democrats, Greens, progressives, socialists, communists, and anarchists all have the right to vote. Lower the high numbers of those voters in California through educating the public and we can slowly pull the state further to the right :-) In the meantime, we have to allow candidates that appeal to the center in order to make any conservative progress at all.
