Obama praising McCain in new McCain spot. Obama react.

UPDATE

DES MOINES, IA–Reacting to the new McCain spot–featuring Barack Obama praising John McCain for his work on climate change, Obama inserted some new language in his stump speech:

“Just this morning, the McCain campaign put out an ad that showed me praising him and Senator Lieberman for their work on global warming – as if there’s something wrong with acknowledging when an opponent has said or done something that makes sense. I think we need more of that in Washington. I don’t disagree with Senator McCain on everything, and I respect his occasional displays of independence.”
