Heh...Obama doesn't want to "seem combative." He only wants to act like a sniveling punk after he got the spit kicked out of him in a street fight, and far away from the opponent who did the spit-kicking, say, "Yeah -- he's not so tough! Yeah -- I can take him! Yeah!"
Honestly -- all of the smack-talking Obama has done after receiving his slobber-knocker just makes him look pathetic.
