I think it’s legit, but hold off on donating just yet. The only reporter to have any firsthand knowledge of its provenance appears to be Post gossip columnist Cindy Adams:

She’s also launching her national political action committee. Registered in Virginia, patterned after Hillary’s HillPac, Sarahpac.com is to support ideas and candidates who share the Palin vision that energy independence is this country’s future.

Next month she addresses a Washington gathering of prominent conservatives. She’s going ahead with a book. Her Facebook page has 410,000 friends. She wants to influence policy knowing the nation must turn to Alaska as its energy resource. She’s planning to be president.

Greta picked it up from there, as did James Pethokoukis at U.S. News, as did wowOwow. But when the Anchorage Daily News dialed the number, all they got was this:

So far, though, the PAC doesn’t appear to be registered with the Federal Election Commission. When I called the number listed on sarahpac.com, I got a message that referred me back to the information on the website. The answering machine message doesn’t say anything about questions from the general public, but it asks reporters with questions about the PAC to leave their name and number.

They were probably planning to roll it out later this week and Adams got a tip that the site was already live, but as I say, hang on to your money until someone confirms it. If it is for real, expect some of the money to go to green causes to help recast the ‘Cuda as a centrist. And the media to pay very close attention to how much money her PAC’s raising compared to Huck’s and Mitt’s.

Adams also claims Palin will be at the Alfalfa Club dinner with Obama that’s coming up; take a gander at the membership roll. Exit question: Will she be “nominated”?

Update: The boss just got off the phone with a spokesman for Campaign Solutions, the site’s registrar, who told her it’s for real and that the PAC papers were filed with the FEC yesterday.
