The third Hollywood star to grace the convention stage Thursday night in support of President Obama used the personal-biography tactic that so many speakers at both conventions have employed this year.

As the daughter of a special-education teacher and an Army base worker, Longoria made it through college through financial aid, Pell grants, loans, and a variety of jobs, she said: “I changed oil in the mechanic shops, I flipped burgers, I taught aerobics classes on campus.”

Her theme: Pursuing the American dream in “a nation that rewards
ambition with opportunity.”

One of 35 campaign co-chairs for Obama’s reelection and a bundler who has helped raise hundreds of thousands of dollars, the “Desperate Housewives” star praised the president for tax cuts she said has helped small business. And she blasted Romney for advocating tax breaks she said would help the wealthy at the expense of the working class.

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