The death Sunday of Robert Dole was a potent reminder of what we have lost as a nation. Another member of the Greatest Generation has left us — another of those Depression-era kids who came together to save democracy in the dark days of World War II. The career of the 98-year-old Kansas Republican reminds us how diminished our nation’s political system has become in the past 25 years. Far fewer supposed leaders are willing to put their nation ahead of their political party. Of course, Bob Dole was no shrinking violet when it came to politics.
