Hand overplayed; game over
Since the release of Unfit for Command: Swift Boat Veterans Speak Out Against John Kerry, Kerry and forces under his command as well as independent operatives have launched a series of strikes, even going as far as hacking Amazon's page. And, of course, the recent Chris Matthew/Keith Olbermann/Michelle Malkin thing.
As regards the latter, I believe it's run its course due to opposing forces having overplayed their hand. Specifically, Keith "Mr. Class" Olbermann is now suggesting that Malkin should "open [her] veins." That is truly beyond the pale, and expect any forces that continue with this battle to have his words used against them.
I suspect that Kerry's forces will recognize that this particular battle should be retreated from and they'll seek to establish new positions. Perhaps they could seek to tie one of the authors' third cousins to wiccanism - better yet, Canadian wiccanism - or something.
