Initially, the Sanders backers appeared ready to defend the vote. One said he viewed himself as an “ally” of the Latino community who was simply trying to get more involved with the caucus. And Sanchez initially refused to resign, arguing that the vote should stand.

However, as the night wore on and speaker after speaker lambasted the “dirty” trick at the convention, the Sanders supporters and Sanchez began to have a change of heart.

Nieves told the Sanders supporters that they were “alienating” people who have been working within the Democratic Party for years.

“You guys are all excited about being progressive and you knock the hell out of people who are (also) progressive and who have been around a while,” Nieves said. “You guys ran all over the place just to be in charge, and you don’t even know what that means.”

Dale Gutierrez, who identified himself as a Iraq War veteran, asked the Sanders supporters why they thought it was a good idea to try to make decisions for the Latino community.

“Do you know what it’s like to be Latino? Do any of you?” he asked.

Anna Hernandez-Valenzia told Sanchez that he would never have the support of the Latino community because of the way he won the chairman’s position.
