In 2000, Edwards unofficially began his presidential campaign when he began to seek speaking engagements in Iowa, the site of the nation's first party caucuses. On January 2, 2003, Edwards began fundraising without officially campaigning by forming an exploratory committee. On September 15, 2003, Edwards fulfilled a promise he made a year earlier as a guest on "The Daily Show with Jon Stewart" to unofficially announce his intention to seek the 2004 Democratic presidential nomination. The next morning, Edwards made the announcement officially from his hometown. He declined to run for reelection to the Senate in order to focus on his presidential run. Edwards's campaign was chaired by North Carolina Democratic activist Ed Turlington.
