I haven't looked at McCain's climate change plan in detail yet, and probably wouldn't know what to say even if I had, so instead, go read Dave Roberts, who concludes, "my initial reaction is that it's better than expected, somewhat short of Lieberman-Warner, and far short of what Obama has proposed. It should comfort us that a McCain presidency will mean real action on climate change, not the shell game Bush is engaged in. But it's hard to see how McCain can claim the allegiance of voters who rank climate change as a top concern."
