Yes, he has and we should appreciate Cheney for his dedication to his career. But, he and other "good conservatives" have been trapped inside a system that has done great harm to our country. Even is they aren't corrupt themselves, corruption has been a part of everyday life inside government. Cheney and others have tried to finesse around the corruption as best they could, imo. However, unless we remove the roots of corruption, it'll go on unabated. Palin understands that, so do we who support her.
