How's this for an indictment?

". . . many of Mr. DeLay’s actions remain legal only because lawmakers have chosen not to criminalize them.”

I don't care for Delay's actions, but he learned what one could get away with in D.C. by watching Democrats get away with it. They controlled the House for 40 years and wrote the book on corruption. If "lawmakers have chosen not to criminalize" such practices, you have to point at them as well as Delay.
