Obama trying to channel Edwards?

From NBC/NJ's Aswini Anburajan
In a populist appeal to Iowans, Barack Obama criticizes unfair trade deals in an new ad "Enough."  

The ad, which will begin running in Iowa today, shows Obama speaking to a town hall size crowd criticizing tax breaks for companies that take jobs overseas.

"If the plant moves to China, and you've been working there for 20, 30 years and suddenly you have the rug pulled out from ya…" Obama says in the ad.   "And you don't have healthcare, and you don't have a pension, you're on your own."

He goes on to say, "We gotta stop giving tax breaks to companies that are moving overseas and give those tax breaks to companies that are investing right here in Iowa."   

The ad, which could as easily have said 'I'm John Edwards and I approve this message,'" appears to be part of a larger push on the economy by Obama, who has been hitting an economic message on the stump recently, showcasing more stories from working Americans, and holding economic roundtables both in Iowa and New Hampshire.
