You know, I can't help thinking that the Democrats can both do some good and drive a wedge between Republicans by using the environment. But Democrats are nuts. They're kind of afraid to make too big of a deal out of the environment. Horrors, some nut on talk radio might call them "tree-huggers." Or maybe "wusses" or something like that. But it's actually one issue that they own which has a lot of bipartisan support.
Today, a bunch of Southern Baptists (of all people) came out in favor of doing something about climate change. And the genuinely creepy Pope Benedict XVI declared that polluting the environment was a mortal sin.
There can't be too much political risk in touting a liberal principle that has the support of Southern Baptists and the Pope, eh?
