I think it’s worth thinking about in the sense that it’s worth remembering that it’s been barely ten years since a Republican won statewide office in California, now it’s unthinkable. Trump will probably end up angering conservatives on some issues the way Arnold did in California as well. National Review is right, he’s not a lifelong movement conservative. Somebody like that can’t get elected nationally, IMHO.
But Trump brings much more to the table than Arnold did. Trump’s a builder, a businessman, he’s not been a politician, but he’s been in the political system for decades, and most importantly he’s a patriot. I believe that he will build a wall and deport the illegal aliens, he will get serious with ISIS, and he will take a sledgehammer to political correctness. Those are the things we need right now in order to survive as a nation.
You don't know Arnold's background very well to see differences here.
