The Monday speech lost Dean the endorsement of Alvaro Cifuentes, the chairman of the Democratic National Committee's Hispanic caucus.
"I have been struggling for the past 48 hours with the performance I saw on TV. I instinctively turned it off after the first few minutes. I respectfully withdraw my present endorsement to Dean's candidacy," Cifuentes wrote in e-mail to the Dean campaign.
Alvaro Cifuentes organized the endorsement of Dean by the Democratic National Committee's Hispanic Caucus leadership. This defection threatens a key part of Dean's Arizona and New Mexico strategy (especially if the other Hispanic Caucus leaders follow suit).
