When I spoke to Blanche Darley, another El Paso delegate, and Paul Moreno's sister, there was no such nuance.

"This is my fifth Democratic Party convention," she said.

"Do you know what PUMA is?" she leaned towards me. "Party Unity My Ass."

According to Wikipedia, it also means "People United Means Action."

Either way, it's trouble for Obama. Tuesday, Clinton supporters will march in support of her, among other activities.

"I'm a PUMA, but that doesn’t mean anything, because PUMAs might not be around after the convention," Darley said.

I asked what she meant. Kicked out of the party? Bolt the party? Come to terms with Obama?

She didn't answer directly.

"We agree and disagree. That's what Democrats are about. At the end we might come together we might not. When you get behind the curtain you can vote for president or skip that race," Darley said.

I told her about a friend of mine who was so invested in Hillary that she wanted to hurt the Democratic Party, and said she was voting for McCain for that reason.

"I'd never vote Republican, never," Darley said.

"But what has Obama done? Has he even proven he's an American citizen? No."

Although Obama has posted a copy of his birth certificate, the story persists that it is not a true copy.

"A Mexican-American would have been crucified if he could not provide his birth certificate," Darley said.

So I asked the next question: Is there enmity between Mexican-Americans and blacks?

"Have the blacks ever stood up on our behalf? On immigration, for example? Yet we always vote to support them," she said. "Don’t get me wrong, I have very good friends who are black. They're different (from the black community)."

Darley complained that people who are not black can join the Black El Paso Democrats, but cannot vote. But anyone can join and vote in the Tejano Democrats, she said.

I asked her about the polls that indicate Obama has wide support among Hispanics. You can say whatever you want, she told me.

Then I took a picture of Ramona de la Paz Torres, a political fixture known as "Monchis."

She too was a Clinton supporter. She just wasn’t so angry about it.
