Excerpted from Sierra Club:
The climate crisis is the biggest challenge facing the next president. But the nation’s top reporters don’t seem to think so. In 2007, they asked 2275 questions. THREE questions mentioned global warming! Sign the petition: tell reporters to focus on the human race, not the horse race. What Are They Waiting for?
Of course when the Democratic debates are sponsored by the coal industry, this sort of crap doesn't come as such a surprise.
