Here’s my conjecture: In part it’s because he seems to like the tension. He likes cliffs, which is why it’s always a cliff with him and never a deal. He likes the high-stakes, tottering air of crisis. Maybe it makes him feel his mastery and reminds him how cool he is, unrattled while he rattles others. He can take it. Can they?
He is a uniquely polarizing figure. A moderate U.S. senator said the other day: “One thing not said enough is he is the most divisive president in modern history. He doesn’t just divide the Congress, he divides the country.” The senator thinks Mr. Obama has “two whisperers in his head.” “The political whisperer says ‘Don’t compromise a bit, make Republicans look weak and bad.’ Another whisperer is not political, it’s, ‘Let’s do the right thing, work together and begin to right the ship.’” The president doesn’t listen much to the second whisperer.
Maybe he thinks bipartisan progress raises the Republicans almost to his level, and he doesn’t want to do that. They’re partisan hacks, they’re not big like him. Let them flail.
