Dean recognized the anniversary in a fundraising email to supporters of the Democracy for America political action committee.
"It's hard to believe it was 10 years ago tonight. On this day a decade ago — January 19, 2004 — I gave one of the most famous speeches in the history of American politics. Or perhaps 'infamous' would be more accurate," Dean wrote in an email with "YEEEAAARRRRRGGGHHHH!!!" as its subject line. "I'm guessing you might remember the climactic moment of that night, as I enthusiastically rallied my presidential campaign supporters in the aftermath of a disappointing finish in the Iowa Caucus."
Dean pointed out that he was right in saying that Democrats were going to take back the White House and go into all 50 states.
"While the 'Dean Scream' became fodder for late night comedians, including a hilarious version by Dave Chappelle I still laugh about, I also feel very proud of the state-by-state preamble to my unforgettable rallying cry," he continued. "Because, when I said we were heading to New Hampshire and South Carolina and Oklahoma ... and to Washington, DC to take back the White House ... it turns out I wasn't kidding."
Dean argued that his scream actually launched a movement that would continue to fuel the Democratic Party into the future.
"In a funny way, that moment was the launch of the 50 State Strategy -- a leave-no-community-behind framework for change that transformed the Democratic Party in the years to come, fueling my campaign to become DNC chair in 2005 and the fight to take back Congress in 2006 and the presidency in 2008," he concluded.
