Four months ago, you took the political world by storm in Iowa. The media were agog. They called your words "gorgeous," your victory "a message to the world." You "made history" and Americans could "look at ourselves with pride" in "a moment to marvel."
Times change. The six weeks leading into Pennsylvania were difficult. You excelled at raising money and gaining endorsements, but got weaker as big problems emerged. Before you can fix them, you must understand them. In Pennsylvania, you won only 30 percent among Catholics and 29 percent among white working-class voters. Defections like this elect Republicans.
Even liberal commentators who adore you warn you can't win with a McGovern coalition of college students and white-wine sippers from the party's left wing. Saying small-town voters cling to guns, faith and xenophobia because of economic bitterness hurt you; it reinforced the growing sense you don't share Middle America's values. So did asking about the price of arugula in Iowa, dismissing the "true" patriotism of people who wear a flag lapel pin, being "friendly" (as your chief strategist, David Axelrod, put it) with a violent, unrepentant '60s radical and having a close relationship with an angry pastor who expressed anti-American sentiments.
