Your third argument is fine, but your others are silly:

McClintock has served the CA GOP for 20 years, while Arnold is a newcomer to the scene.

Arnold has been a professed Republican for decades. No, he has not been an elected politician, but he has expressed his preference in circumstances when it would have been far easier to claim to be a Democrat or not to say anything. He hasn't been an elected official or "served" like McClintock, but don't make it sound like he joined the GOP last week.

McClintock was in this race first, while Arnold joined late in the game.

This isn't fair either. It was only a couple of days. It's not like Arnold was pulling a Wesley Clark.

I don't disagree with either of your responses. However, the poster to whom I responded claimed that McClintock isn't even a Republican. My intent was only to point out the absurdity of such a claim.
