That's Al Gore's take anyways -- and he's got a point. In an op-ed over at the Huffington Post today, Gore points out that reasonable debate over how to address pressing problems (climate change and how to deal with the nation's debt problem) has been hijacked by "ideological extremists". An overwhelming majority of scientists tell us that climate change is being caused by human activity. Economists everywhere have outlined the dangers of defaulting on our national debt obligations. And yet, a handful of lunatics with their heads in the sand flat-out deny both -- with dangerous consequences for the nation.
