Brad Johnson noted earlier this week that all but one of the Republican candidates for U.S. Senate “dispute the scientific consensus that the United States must act to fight global warming pollution.” Now, that lone climate realist — Delaware Rep. Mike Castle — has been knocked out. So make that all GOP candidates for U.S. Senate deny the need for climate action.

Tea Party upstart Christine O’Donnell, who took out Castle to become the Republican nominee for Senate in Delaware, is right in line with her GOP colleagues on the climate issue. She has attacked climate legislation as a “cap and tax energy scheme which would kill 6,117 Delaware jobs.” Sarah Palin, who endorsed O’Donnell and deemed her a “mama grizzly,” noted approvingly that the candidate is “against Obama’s cap-and-tax scheme.”

O’Donnell is also against masturbation, as she explains in a 1996 MTV special about a pro-abstinence campaign she was involved in. “The Bible says that lust in your heart is committing adultery. So you can’t masturbate without lust,” she said. “… If he already knows what pleases him and he can please himself, then why am I in the picture?”

Why is she in the picture, indeed? Many Delawareans may be asking themselves that very question this campaign season.
