Greg Dobbs, who left KNRC earlier this year after an ultra-gross health scare, was a political progressive by Denver talk-radio standards, yet he wasn't a knee-jerk pinko. He was able to eloquently express his opinions even as he equitably refereed debates between people who disagreed with him and individuals supporting his point of view. In other words, he epitomized KNRC's promise to present both sides of issues -- a pledge that's looking awfully one-sided since Dobbs's departure.
