President Obama raised his speechifying game Thursday night, as he had to do. Another billet doux inviting hostile congressional Republicans to please sit around the campfire and sing “Kumbaya” wouldn’t have cut it. What Obama did, instead, was issue a challenge -- and, not incidentally, lay out the opening themes of his reelection campaign. Perhaps the most significant line in Obama’s speech was his promise to take his jobs message to the people in “every corner of the country.” He told the assembled members of Congress that if they balk at passing his American Jobs Act, he will go over their heads.
