Gibson's third abysmal failure in the gotcha game was after Palin stated clearly and unambiguously that she beieved human activities contributed to global warming, with its relative contribution uncertain. Poor guy. So he says you once said you didn't believe it, so (essentially) you must just be lying to accommodate McCain's position. Sorry, Charlie, she showed she could assess accumulated evidence. Deal with it. Is this guy the best we've got these days?
