Only one green candidate?

John McCain’s pick of Sarah Palin may have endeared him to hockey moms, but it’s taken the GOP ticket out of the running in the green sweepstakes, argues New York Times columnist Thomas Friedman.

By choosing Palin, who supports drilling in the Arctic National Wildlife Refuge (McCain has opposed it, although he’s now reconsidering) and doesn’t believe in human-caused global warming (McCain does), McCain “has completed his makeover from the greenest Republican to run for president to just another representative of Big Oil.”

And Friedman notes that for all of McCain’s stump talk about boosting clean renewables, he has studiously avoided supporting eight different votes to extend crucial tax credits for wind and solar.
