Have you seen this Rasmussen poll? Only 24 percent of Americans consider Al Gore an expert on global warming, 47 percent say he isn’t.

Hmm. Is the famous Gore effect about to kick in? You’ll recall that, as soon as Al decided that Howard Dean was an unstoppable force and announced he was endorsing him, Dean imploded, went berserk in Iowa, and that was that. Could it be that Gore is about to do to “climate change” what he did to the Dean campaign? Another week or two of Al’s proselytizing and that polar bear on the ice floe will be like Mad How in the New Hampshire primary – adrift and heading south and howling incoherently.
