In September 2003, retired four-star general Wesley Clark announced his intention to run in the presidential primary election for the Democratic Party nomination. His campaign focused on themes of leadership and patriotism; early campaign ads relied heavily on biography. His late start left him with relatively few detailed policy proposals. This weakness was apparent in his first few debates, although he soon presented a range of position papers, including a major tax-relief plan. Nevertheless, the Democrats did not flock to support his campaign.

Which Democratic nominee declared his intention to enter into the presidential race, in the fall of 2003?
