A pair of Hollywood actors/red-carpet luminaries stepped up as celebvocates for Obama on the convention stage Thursday night.

Kerry Washington’s credentials: “I’m here not just as an actress, but
as a woman, an African-American, a granddaughter of immigrants who came here through Ellis Island, a person who could not have afforded college without student loans,” said the George Washington University grad. 

Speaking with the fiery clarity she brings to her role as a cutthroat Washington crisis-management fixer on ABC’s “Scandal,” Washington worked a “we the people” theme: “We’ve expanded the meaning of that phrase to include more and more of us. That’s what it means to move forward.” And she chastened anyone who is “too busy” to get involved. “You may not be thinking about politics, but politics is thinking about you. . .The other side wants to take our voices away and render us invisible. But we are not invisible.”

As for Scarlett Johansson, the former child actor turned bombshell
thespian, she described herself as “a representative of the many millions
who depend on non-profit programs to help them survive” – the product of a family that moved every year and “barely made enough to get by.”

In smoky eyes and a gray blazer over a tight flag-themed t-shirt, she
urged young people to “commit” to the political process, describing her
thrill as a little girl when her mother would take her into the voting
booth. She described her pride at “finally” getting to vote during the last
election – but maybe she meant the one before that: At 27, the star was eligible to vote in the 2004 cycle as well.
