Reductio ad absurdum: After two years of taking his base for granted, the former Pied Piper of America’s youth had to spar with Jon Stewart to try to get the attention of young people who once idolized him.

Obama still has the killer smile, but he’s more often sniffy than funny. When Stewart called White House legislation “timid,” Obama got defensive and offered a less-than-thrilling new mantra: “Yes, we can but …”…

His arrogance led him to assume: If I build it, they will understand. He can’t get the gratitude he feels he deserves for his achievements if no one knows what he achieved and why those achievements are so vital.

Once it seemed impressive that he was so comfortable in his own skin. Now that comfort comes across as an unwillingness to be wrong.
