So Schwarzenegger endorsed McCain today, citing his fight against wasteful spending, his "vision" for protecting the environment ("and the economy simultaneously"), and his national security credentials.
Of course McCain’s battle against earmarks is entirely symbolic, given that they are a tiny sliver of federal spending. His "vision" on global warming amounts to an outdated and weak cap-and-trade program coupled with massive subsidies for nuclear power (which, of course, is not wasteful government spending, not at all). And his national security credentials mainly consist of having once fought in a war and consistently, ever since, advocating to start more.
But hey, I bet Arnie was just relieved not to have to deal with Romney.
