Yes, Barack Obama attacked the establishment too, and he even uttered a wisecrack from time to time. But what the Democrat really scored with was his unflagging commitment to maximally generic uplift. “Yes, we can!” he exclaimed at rally after rally, his message as upbeat and unchanging as an “Attitude is a little thing that makes a BIG difference” poster that has been hanging in some accounting firm’s lobby for the last 20 years. Obama wasn’t afraid to embrace such earnestness. He didn’t worry about looking uncool, naive, embarrassingly sincere. And apparently at least 68.9 million Americans were primed for someone exactly like that.
