Mr. Ehrlich's counterattack on Mr. Barnes was no lofty riposte. He called the former congressman "a gun for hire" whose views on gun control are "on the far-left fringe of the Democratic Party"; and he accused Mr. Barnes of conspiring with Democratic candidate Kathleen Kennedy Townsend to tarnish Mr. Ehrlich with "a very negative set of ads." The Townsend camp was quick to deny any involvement with the radio attack -- but what does Ms. Townsend think of it? Silence won't do; does she agree with Mr. Barnes's labeling, or not?
