In The New York Sun and his blog at National Review Online, Jim Geraghty writes that Wal-Mart now has what he describes as "a presidential-campaign-style war room":

Various unions want to organize Wal-Mart workers. They’re welcome to try, just as the corporation is welcome to try to persuade its workers that it’s a bad deal for them in the long run.

But the anti-Wal-Mart forces have been, depending on your point of view, remarkably innovative, remarkably below-the-belt, or perhaps both. And the company has responded with its own public relations effort to defend its reputation, a presidential-campaign-style war room.

If every big and/or controversial company in America isn’t looking at this p.r. strategy, they ought to be – Halliburton, Microsoft, pharmaceutical companies, the oil industry, health care providers. Traditional p.r. methods may not be up to the challenge of a world of the blogosphere, attack documentaries, talk radio, bookshelves groaning under the weight of angry tomes, etc. When there isn’t a political campaign going on, there will be these surrogate campaigns – except in these, there are no election days, just a continuing cycle of attack and counterattack.

If you think you're big enough to warrant one...take it as a sign to start setting up shop.
