Sometime last year, I remember watching a video of Barack Obama addressing his campaign staff in Chicago. The talk took place after Obama had won the Democratic primary. It was a pep talk, and the theme was, “Now it’s really serious, we have to win.” One thing Obama said stood out. He said that if John McCain won, none of the important issues facing the country would be solved, and he singled out climate change. I don’t care what McCain promises, Obama told his staff, if he wins, he’s not going to do anything about it.
