CHARLOTTE, N.C. -

Actress Eva Longoria says she changed oil in a mechanic's shop, flipped burgers at Wendy's, and taught aerobics to pay off her college loans. She needed a tax break back then, but not anymore.

President Barack Obama will ensure that hard work and ambition are rewarded with opportunity, the "Desperate Housewives" star said Thursday at the Democratic National Convention.

Obama has cut taxes for working Americans and small business owners, Longoria said, while Republican presidential candidate Mitt Romney wants to cut taxes for wealthier people like her.

Romney, however, has said he will not raise taxes on the middle class.

Longoria, a co-chair for Obama's re-election campaign, says she has traveled the country for the president and has been struck by how optimistic people are.
