RADIO GA-GA JASON ZENGERLE’S ARTICLE was a fair piece of work ("Talking Back," February 16). Democracy Radio may succeed, who knows? But black people are an important component of the Democratic Party and the left-wing coalition, and I doubt if they will give up black radio for Al Franken. This absence of an important listener constituency is likely to affect Democracy Radio’s programming and tone. The stereotypical white, affluent, professional Democrat is going to be difficult to lure away from National Public Radio, which is an audio bulletin board for liberals.
