"If American workers are being denied their right to organize when I'm in the White House, I will put on a comfortable pair of shoes and I will walk on that picket line with you as president of the United States."

-- Barack Obama, quoted by Slate, while making a campaign speech in 2007.

The president is a very cautious man. Everything is discussed, analyzed and ruminated upon. But some things? For some things, you really want a leader, and I can't think of one good reason why Barack Obama can't go to Wisconsin. If he were a Republican, he would simply say, "I made a campaign promise and I have to keep it."

Mr. President, just this once, I actually want you to think like a Republican. Keep your promise -- and don't apologize for it.
