CAP & TRADE was Obama's answer to "global warming". Under CAP & TRADE, you could pollute all you want so long as you purchased "carbon credits" controlled by the government. Our elected officials would of course determine which "carbon credit" marketers (the ones they invested in) would be allowed to sell these credits. In the purchase price of these "carbon credits" would be the taxes the government would impose on them. See how nicely that works.
