F.Y.I. Palin is on record for both LOST and carbon credits.
LOST.
"Q: Let me clear something up: Sen. McCain has said he supports caps on carbon emissions. Sen. Obama has said he supports clean coal technology, which I don’t believe you’ve always supported. Do you support capping carbon emissions? PALIN: I do. I do."
