Sen. McCain backed action to counter global warming, calling on Americans to push for green technology innovation and entrepreneurship. He pointed to his sponsorship of the McCain-Lieberman climate bill as a claim that he’s taken more environmental action than the Democratic presidential candidates, though McCain’s lifetime environmental score, given by the League of Conservation Voters, is just 24% compared to 86% for Obama and 87% for Clinton. McCain also called himself a “Teddy Roosevelt Republican”, implying that he’s an environmentalist.
