Bruce Bartlett, author of Impostor: How George W. Bush Bankrupted America and Betrayed the Reagan Legacy, has launched a new blog, Bartlett’s Notations. Bruce is a principled and well-respected supply-sider who calls things as he sees them, even when it causes a stir, as his book did (see also here). He is worth reading whether or not one agrees with his outlook or conclusions. Welcome to the blogosphere Bruce!
