Hillary Clinton has taken a "conservative" strategy throughout her campaign for president, both in style and in substance. She hasn't come out with many policy goals that could be called truly innovative, but at the same time she has tried to play both sides of the fence on a number of issues, especially foreign policy. Most recently, she pleased many hawks by refusing to sit down with some of America's enemies.
Ed Crane over at the Cato Institute recently made a compelling case that, rather than being a left-liberal, Hillary Clinton is most comfortable with the "national greatness" neocons. Read Crane's argument here.
