Save to FavoritesMartin O’Malley remembers running for president like this: He is on a train, heading for a bridge. He can see the bridge is giving out. He is shouting and waving and pointing at a “better lane,” he says. “But it’s like I couldn’t get anybody on the train to listen.”
“It was the most frustrating experience I’ve ever had in politics.”
