I found this article on Huffington Post indicating that the site was back up and that members of the organization had played significant role in supporting Sarah Palin from within the McCain campaign.
PNAC: Palin's Pentagon In Waiting?
Many of its members served as advisers to John McCain's presidential campaign. Bill Kristol is still listed as PNAC's chairman, and is known to be "exceptionally close" to the senator. McCain's top foreign policy aide, Randy Scheunemann, serves as PNAC's project director. McCain spokesperson Michael Goldfarb is also listed as a PNAC research associate. ...
Among those associated with the McCain campaign, Kristol, Scheunemann, and Goldfarb are known to have been three of the biggest Sarah Palin boosters. It was reported that Scheunemann had even been fired by the campaign after it was discovered that he was leaking information favorable to Palin to the press. ...
After lobbying McCain to pick Palin as his VP, Kristol then used his prominent position as a New York Times columnist to promote Palin and criticize the McCain team's handling of her.
