I love this ad that the Cato Institute ran in major newspapers across the country. They have this blurb alongside it on their website:
"President Obama says that "economists from across the political spectrum agree" on the need for massive government spending to stimulate the economy. In fact, many economists disagree. Hundreds of them, including Nobel laureates and other prominent scholars, have signed a statement that the Cato Institute has placed in major newspapers across the United States."
