I couldn't agree more with Mr. Hills assessment that Obama needs to acquire some of the traits of his tenacious predessors including, as Mr. Hill suggests, the king of the political fight ,LBJ. But the big problem is that LBJ did not have to content with the professional lobbyists as they exist today nor soft and hard money abused legally by our elected officials. Obama's task on the reformation of heath care would be much easier without all the PAC money and influence of pro lobbyists as it would limit the reach of the lies and distortions into the heart of the citizens of our country.
