From James Taranto:

Theoretically, Obama was on the side of the government employee unions that were behind the unsuccessful attempt to oust Gov. Scott Walker, who last year signed legislation abolishing most of their corrupt "collective bargaining" arrangements. "Understand this," the future president declared in 2007: "If American workers are being denied their right to organize and collectively bargain when I'm in the White House, I'll put on a comfortable pair of shoes myself, I'll will walk on that picket line with you as president of the United States of America. Because workers deserve to know that somebody is standing in their corner."

In practice, Obama tweeted "present": "It's Election Day in Wisconsin tomorrow, and I'm standing by Tom Barrett. He'd make an outstanding governor." But he was only theoretically present. Not only was he standing, not walking; he was standing someplace far from Wisconsin. In fact, for all we know he was sitting at the time. We can't be sure he was even wearing shoes.

Heh. Read it all.
