Excerpt:Â 1. We expect promises of change from Democratic candidates, but it's disappointing to watch certain Republican candidates yield to that superficially seductive sound bite, too. It's like the global-warming freight train, which few politicians have displayed the guts and character not to board. 2. It's disappointing to watch candidates from both parties accept the premise that criticizing your opponents' records and pointing out their inconsistencies and lies is engaging in dirty politics. It is not dirty but obligatory to draw distinctions between you and your opponents. Dirty politics is distorting one's record or spreading lies about a candidate. Why do so many refuse to see the difference? It's the same type of shallow thinking that prefers that politicians get along rather than promote their ideas.
