For you "A Team" of climate change analysis, you should always rely on
Grist's Dave Roberts rather than me. His
conclusion about McCain's proposal is that "it's better than expected, somewhat short of Lieberman-Warner, and far short of what Obama has proposed." On climate, interestingly, there's a clear choice between the two candidates
and both candidates would be substantially better than Bush. Which shows you, I guess, how terrible Bush has been.
