Democrats apparently attempted to burnish their green credentials last night at the debate by recycling questioners:

Catherine Jackson, there with her son Chris, said her son has served three tours as a soldier in Iraq. She's worried about the U.S. going to war in Iran and her son being called to serve there as well. What will the candidates do to prevent a war with Iran? 

Now when have I heard that before? How about in May. Thank you Harry Reid.

"My son was in Iraq three times," said Catherine Jackson of Las Vegas. "I thank God he's home now. Enough is enough. We need to bring our troops home."
