and this
"What rekindled my interest, however, was the buzz on Monday over the coal industry's sponsorship of at least three CNN debates. If you missed it, the coal industry has created a front group called Americans for Balanced Energy Choices (ABEC) which has a $35 million ad budget in states with primaries and caucuses to snow the public on the idea of "clean coal."
What is most disturbing, however, is the fact that, in those three debates -- including the one Monday night in South Carolina, as well as the CNN/YouTube debates in Nevada and Florida -- not one question was asked about global warming."
