in a Lockheed S-3 Viking, where he gave a speech announcing the end of major combat in the Iraq war. Clearly visible in the background was a banner stating "Mission Accomplished". Bush's landing was criticized by opponents as being overly theatrical and expensive. The banner, made by White House personnel (according to a CNN story:) and placed there by the U.S. Navy, was criticized as premature. Nonetheless, Bush's approval rating in the month of May rode at 66%, according to a CNN-USA Today-Gallup poll. On May 3, 2003, Democrats met at the University of South Carolina in the first formal debate between the nine challengers for the nomination. The candidates disagreed on the war against Iraq, health insurance, President Bush's tax cuts, but united in criticizing Bush's handling of the economy.

Though this was almost two years before the Iowa Caucus, Dean hoped the early start would give him some much needed name recognition. As a governor of a small state, Dean was not well known outside of New England. In December of that year, John F.

Additionally, many other candidates announced their intention to form committees (a formality usually indicating an official run): U.S. Sen. John R. Edwards of North Carolina, U.S. Rep. Richard A.
