Lawrence Kudlow, an all-time Friend of the Blog, highlights the importance of coal as an economic and political factor:
The coal story is so important simply because the U.S. has massively undeveloped coal resources. With 27 percent of the world's coal reserves estimated at 270 billion tons, the U.S. is the Saudi Arabia of coal. And yet cap-and-trade would destroy this critical sector.... Sen. McCain, who favors cap-and-trade, has not yet spoken directly to the coal issue, or for that matter to the various ways that coal and natural gas can be liquefied and turned into clean fuel. But this could be an important political point for McCain.
