This morning, I joked on Fox and Friends that San Francisco acts like a truth serum on Barack Obama. It’s where he trashed western Pennsylvanians as Bible-thumping racists clinging to their guns and religion. And it’s where he told the SF Chronicle that he plans to bankrupt coal companies and engineer huge energy price shocks to save the planet. (background links here and here)

Allah clipped the F&F video — watch here — and notes that Sarah Palin riffed on Obama’s San Francisco candor this morning:

“There must be something about San Francisco,” she said. “I heard on Fox News today, it’s like a truth serum where when he’s there, he seems to be more candid.”

It was at a San Francisco fundraiser earlier this year that Obama got into trouble, suggesting rural voters “cling to religion and guns” because jobs were being lost. Palin referred to them Monday as “bitter clingers” and “cling-ons.” (There goes the Star Trek vote?)

And it was Obama’s comments to the San Francisco Chronicle on fees for coal emissions that brought on Palin’s most recent attacks.

“So he’s talking to the San Francisco Chronicle, and he says that sure, if industry wants to try to build these coal-fired power plants, they can go ahead and try, but they’re only gonna be able to do it in a way that bankruptcies the whole industry, the coal industry,” she said. “Now he’s comfortable with this happening.”

Meantime, the Ohio Coal Association weighs in:

Mike Carey, president of the Ohio Coal Association (OCA), today issued the following statement in response to just-released remarks from Senator Barack Obama about the nation’s coal industry.

“Regardless of the timing or method of the release of these remarks, the message from the Democratic candidate for President could not be clearer: the Obama-Biden ticket spells disaster for America’s coal industry and the tens of thousands of Americans who work in it.

“These undisputed, audio-taped remarks, which include comments from Senator Obama like ‘I haven’t been some coal booster’ and ‘if they want to build [coal plants], they can, but it will bankrupt them’ are extraordinarily misguided.

“It’s evident that this campaign has been pandering in states like Ohio, Virginia, West Virginia, Indiana and Pennsylvania to attempt to generate votes from coal supporters, while keeping his true agenda hidden from the state’s voters.

“Senator Obama has revealed himself to be nothing more than a short- sighted, inexperienced politician willing to say anything to get a vote. But today, the nation’s coal industry and those who support it have a better understanding of his true mission, to ‘bankrupt’ our industry, put tens of thousands out of work and cause unprecedented increases in electricity prices.

“In addition to providing an affordable, reliable source of low-cost electricity, domestic coal holds the key to our nation’s long-term energy security – a goal that cannot be overlooked during this time of international instability and economic uncertainty.

Spread the word. It’s not too late.
