Another poll shows widespread public support for carbon regulation - how should Democrats proceed?

Your contention that "Limit pollution, invest in domestic energy sources and encourage companies to use and develop clean energy" is synonomous with belief in AGW is incorrect. If you asked most people if they liked puppies, you would probably get an even larger majority. The fact is that if you ask people honestly if they are willing to be taxed to help pay for unproven technology, increase foreign dependence on oil, and have fewer choices an lesser freedom, the actual truth, you wouldn't even get most democrats to agree. That is why the far left depends on deception.
