In the political paraphernalia department, "Yes, we can" is becoming "No, he can't." Anti-Obama memorabilia -- from T-shirts to bumper stickers to buttons -- is increasingly emerging in the marketplace as the president's economic and health care policies polarize supporters and detractors. While "Mama for Obama" was a popular slogan during the 2008 election cycle, that design has been retooled with angry and fickle disenchantment: "To the Mama for Obama -- thanks for the tax hike." The "Audacity of Hope," the title of Mr. Obama's popular book, has been replaced by the "Audacity of Hype."
