The left is debating right now whether Barack Obama’s cabinet appointments imply a betrayal of left-wing principles. Chris Matthews discussed this topic on “Hardball” last night and concluded that Obama’s appointments are window-dressing. They are there to provide cover for Obama as he implements a left-wing agenda. I can’t say whether or not Matthews’s theory is correct, but we will find out soon enough. In the meantime, it will be interesting to watch this debate unfold. You know change is afoot when Hillary Clinton is considered to be your right-wing foil.
