Who do you like for President? Many Americans this year seem inclined to answer that question with another: What’s today? The polls are volatile. We’ve already seen surprises, and we’ll see more. This was going to be a column endorsing Romney. The straight-arrow entrepreneur is my guy. If Mitt quits, I’m for gruff Fred Thompson. I was also going to say that McCain and Huckabee, big-government egotists, are my least favorite—though preferable to any Democrat.
