I've just written a column about this to be syndicated by Blue Ridge Press, so I won't tip my hand yet...but instead I'll ask: What do you think? If it's a McCain-Clinton or a McCain-Obama race--i.e., a race in which both candidates care about addressing climate change--is that good for the issue (because it ensures that we'll get action in 2009) or bad for the issue (because global warming will seem to have been neutralized, even though there are actually significant differences between McCain and the two Dems)?
