President Barack Obama's campaign seized a golden (or should we say yellow) opportunity to attack rival Mitt Romney after the Republican presidential candidate vowed to end federal funding for public broadcasting during last week's debate.

In a new political ad, images of convicted financiers flash by as a narrator states: "Bernie Madoff. Ken Lay. Dennis Kozlowski. Criminals. Gluttons of greed. And the evil genius who towered over them?  One man has the guts to speak his name (with a shot of Romney). Big Bird!"

The narrator continues, "Big. Yellow. A menace to our economy.  Mitt Romney knows it's not Wall Street you have to worry about - it's Sesame Street."

Then the commercial shows Romney at the debate vowing, "I'm going to stop the subsidy to PBS."

The narrator has the final few words: "Romney: taking on our enemies no matter where they nest."

Despite the threat to its network, PBS isn't supporting the commercial. The company issued the following statement: "Sesame Workshop is a nonpartisan, nonprofit organization and we do not endorse candidates or participate in political campaigns. We have approved no campaign ads and, as is our general practice, have requested that the ad be taken down."
