What has been set up, methinks, is Edwards/Clinton. But the bet is hedged by Kerry/Clark.
Still, though, I'm inclined to believe Clark may be running his own operation -- separate from, and probably antithetical to, the Clintons'.
The Democrat frontrunners have been successively shot from behind. A by-product will be the extended relevance of the Democrat primary season -- a Bush-bashing extravaganza, with wall-to-wall media coverage and cheerleading (a no extra cost option).
Nor is there yet a target for the GOP to fire back at. The flanks of these oh, so vulnerable targets are thus protected by the gauze of uncertainty.
There is a masterful political operation going on here...
