Among the many postmortems and pontifications after Tuesday’s midterm elections, this one from a USA Today editorial resonates: “President Obama has often seemed smaller than the job in ways that rattled Americans and drove down his approval ratings. If you’re going to govern as a vigorous advocate of a large and activist government, which Obama is, then the government has to be seen as helpful and competent, which it isn’t.” Words to remember, given government’s increasing reach … And among the political flubs and faux pas before the election — so many to choose from — Sen. Mary Landrieu’s is a standout. In an interview with NBC News, the Louisiana Democrat remarked, “I’ll be very, very honest with you. The South has not always been the friendliest place for African Americans. It’s been a difficult time for the president to present himself in a very positive light as a leader.” Never mind the obvious slap to her constituents as the Louisiana Senate race heads into a December runoff. Ms. Landrieu’s own campaign distanced itself from President Obama. … Next to Mr. Obama’s own post-Election Day hangover, Vice President Joe Biden’s must have been a head-pounder. After all, Mr. Biden assured before the election, “If you look at every single major issue of the campaign, the American people agree with our position.” In reality, not so much. But don’t expect any “temperance” from Biden. No, he’ll probably indulge in more of the “hair of the dog” that bit him.
