In the ensuing years, he took a lot of grief from said Clinton supporters, like Paul Begala, James "crazy ass pit viper" Carville, and others. Most of the grief came for his support of a 50-state strategy, the idea that Dems should run in every county of every state. This was seen as folly by many of the Democratic establishment—the same establishment, mind you, that gave us 8 out 0f 12 electoral losses in the past half century. Begala had this to say the strategy, "What he has spent it [DNC money] on, apparently, is just hiring a bunch of staff people to wander around Utah and Mississippi and pick their nose."
As should be evident by now, Dean and his strategy have been more than vindicated. We have more Democrats and better Democrats in more parts of the country than at any time since the 60s at least. There's a deep bench of talent and a stronger progressive movement ready to push the next congress and president to move the country in a saner direction. Obama and his team hewed to the same strategy and now we have McCain fighting for life in places like Montana and N. Dakota, Indiana, and Virginia.
So, kudos to you, Howard Dean, you—and those who followed your lead—rocked the mother fucking house.
