If the Democrats had such title as Miss Latina America, it undoubtedly would go to actress and political activist Eva Longoria.

The 37-year-old who came to fame with the TV series “Desperate Housewives” has been all over the Democratic National Convention as the leading Latina surrogate for President Barack Obama.

On Thursday night, she was the Democrats’ answer to Clint Eastwood, promising “”No empty chairs” – and telling reporters ahead of time that this would ““probably the most important speech I’ve ever done in my life.”

Of course, I would have voted for the scene on “Housewives” where Eva as Gabrielle Solis found out she was pregnant and told her husband that she planned to get fat in honor of his mother.

Or maybe the scene where she has to break the news to her daughter Juanita that she’s Mexican.

“Really, so we’re like those people who sell oranges on the side of the road?” asks Juanita.

“I do not understand – how could you not understand,” Gabriella tells her daughter. “We eat Mexican food all the time… You do know you’re a girl… (and cutting off her husband’s objection) half the women in your family have mustaches. It could be very confusing. (And sending Juanita off to play with her sister) And while you’re at it, tell he she’s Mexican, too.”

Clint Eastwood, she all but said in interviews, can’t do that kind of comedy – nor wear four-inch Louboutin stilettos, not that we know of.

“[Eastwood] had a different narrative,” she told the “Today” show. “Everyone keeps comparing us because we’re both from the entertainment industry, but I’m a co-chair for the campaign. I’m on the ground. I’ve been in swing states.

“I’ve been talking to the American people, I’ve been out there speaking on behalf of Obama’s record. I’ve been in the trenches.”

But on Thursday night, Longoria sounded as is perhaps she had left her best lines and best thoughts in all her interviews.

“I feel fortunate to be standing on this stage tonight,” she said. “I never could’ve imagined it growing up. I was born in Corpus Christi, Texas, the youngest of four girls, including my oldest sister, Lisa, who has special needs. My mom was a special education teacher, and my dad worked on the Army base. We weren’t wealthy, but we were determined to succeed.”

She was touching and even funny in talking about how her family stressed the importance of education and how she worked hard to pay her student loans.

“I changed oil in a mechanic shop, flipped burgers at Wendy’s, taught aerobics and worked on campus to pay them back.

Longoria said she is representative of all who have fought to achieve the American Dream and has achieved a level success where she no longer needs the kind of financial breaks Mitt Romney seeks to give to others like her.

“He would raise taxes on middle-class families to cut his own—and mine,” she said. “That’s not who we are as a nation, and here’s why:

“The Eva Longoria who worked at Wendy’s flipping burgers — she needed a tax break. But the Eva Longoria who works on movie sets does not.”
