WASHINGTON (CNN) - Portraying himself as the only candidate that can bring change to Washington, Sen. Barack Obama, D-Illinois, released a new television ad Wednesday.
"I approve this message to ask you to believe - not just in my ability to bring about real change in Washington," says Obama in the ad. "I'm asking you to believe in yours."
Obama, who has promised not to take money from lobbyists, has said he will work to reduce the influence of special interest groups on lawmakers. He continues to promote that idea in his ad.
"Every time I speak about my hope for America, the cynics in Washington roll their eyes," Obama says. "You see, they don't believe we can actually change politics and bring an end to decades of division and deadlock. They don't believe we can limit the power of lobbyists who block our progress, or that we can trust the American people with the truth."
The ad starts running in Iowa Wednesday.
