POLITICAL FOOT-DRAGGING in the Jon Corzine probe? Well, he is one of Obama’s top bundlers. Plus: “Again, the probers no doubt want to do the right thing, but the heads of the investigative agencies can hardly be described as impartial. Many are presidential appointees or at least have a vested interest in helping Obama avoid a major embarrassment. The publicity hungry and hyper-ambitious Preet Bharara, the US attorney for the Southern District, as well as the heads of the Securities and Exchange Commission and the Commodity Futures Trading Commission, are all longtime Democrats. Some, like Bharara, are fairly partisan Democrats looking for bigger future jobs. They have much to gain if the investigation doesn’t blow up before Election Day — so it’s pretty convenient that they keep hitting what we’re told are dead ends.”
