(CNN) – President Barack Obama's presidential campaign is using a radio ad to target black voters, who overwhelmingly voted for him in the 2008 election and who he'll need to win again in 2012.
In the spot, a male announcer says, "Four years ago we made history. Now it's time to move forward and finish what we started together. We have to show the president, we have his back."

Singers in the background proclaim, "We've got your back."
Later, the spot uses a clip from a speech Obama delivered in May: "I refuse to pay for another millionaire's tax cut by kicking children off of Head Start programs; asking students to pay more for college; or eliminating health insurance for millions of poor and elderly and disabled Americans on Medicaid."
In 2008, 95% of African American voters cast ballots for Obama, and made up 13% of the total electorate, according to national exit polls.
