Mr. Obama has become actively bad at politics. Here is an example of how bad. Anyone good at politics does not pick a fight with the Catholic Church during a presidential year. Really, you just don’t. Because there’s about 75 million Catholics in America, and the half of them who go to church will get mad. The other half won’t like it either…

A smaller example. If you’re good at politics, you don’t humiliate a friend and ally who popped off about your campaign strategy. You don’t send Cory Booker on a rhetorical perp walk and make him recant. You quietly accept his criticism, humbly note your disagreement, hold a grudge, and keep walking.

A more important example, and then we’ll move on. The president opened his campaign with a full-fledged assault on his opponent. This is a bad sign in an incumbent! An incumbent should begin his campaign with a full-fledged assertion of the excellence of his administration—the progress that has been made, the trouble that has been avoided, the promise that endures. You’ve got to be able to name these things. Then, once you’ve established the larger meaning of your administration—with wit and humor, and in a tone that assumes fair minded Americans will see it your way—you turn, in late summer, to a happy, spirited assault on the poor, confused, benighted and yet ultimately dangerous man running against you.

The president’s campaign is making him look small and scared.
