There's been an interesting conversation happening about why the GOP is the only major right-of-center political party that doubts the science behind global warming. . . . This isn't a very popular statement, but there is a role for elites in public life. Just like I want knowledgeable CEOs running companies and knowledgeable doctors performing surgeries, I want knowledgeable legislators crafting public policy. That's why we have a representative democracy, rather than some form of government-by-referendum. But of late, the elites in the Republican Party are abdicating their roles, preferring to pander to the desire for free tax cuts and the hostility to Al Gore than make tough and potentially unpopular decisions to safeguard our future. —Ezra Klein, "The Failure of Conservative Elites"
