Green McCain?

I just saw John McCain on Letterman, he used it as a soapbox, but hey he is politician. He spent the first part preaching about how global warming is real (a stark contrast to most of what his party has said) and how we need to do something about it by increasing the use of hydrogen, fuel cells, wind, etc. It is down right odd hearing this from a republican, but McCain is pretty much a centrist so I guess it makes sense. I will admit that I trust McCain more than *anyone* in the Bush administration; with all the public appearances he has made I think it’s pretty obvious he will run for president. Depending on who is running on the democratic ticket I would consider voting for McCain, mainly for his fiscal responsibility and Green views.
