Apropos of this article, I'd like to propose a rule of thumb -- call it the Bloomberg law. If someone is mentioned as a potential candidate for a national office for both parties, he should be a candidate for neither. The differences between Democrats and Republicans are so huge these days that someone who has major policy areas attractive to both parties will also hold views each party finds repellent. This isn't true, I should say, in the case of figures outside politics whose views are just unknown (though even in that case I'd be skeptical of them as candidates). --Sam Boyd
