Here's "Level," Sen. Hillary Clinton's first ad up on the Pennsylvania airwaves.

Here's the script. Mr. Obama, who also blasts "special interests" on the campaign trail, has been up on TV in the state for a week, and radio for longer.

Announcer: She's fighting for America's middle class.

Hillary Clinton: It's time to level the playing field against the special interests.

Announcer: She'll end $55 billion dollars in giveaways to corporate special interests and invest it in middle class tax cuts and creating new jobs. She'll get tough on unfair trade deals and end tax breaks to companies that ship jobs overseas.

Hillary Clinton: Standing up for people who weren't getting a fair shake, that's been the
purpose of my life. And it will be the purpose of my presidency.
