I know things seem really discouraging, and I've said in the past that the Gonzo-meter stuff is silly, and now you appear to agree with me. But things aren't over yet. The Judiciary committee finally issued their subpoenas, so we're on to the next step, finally.
After this, the White House will fight the subpoenas. If they win, Gonzales is safe through 2008. But if they lose, they will try to negotiate with the Democrats to limit testimony and try to keep Rove out of jail. That's when Gonzales will become a bargaining chip.
I don't know how long the appeals process will take to play out. I suspect things will be done in a few months. So plan to revive the Gonzo-meter in the fall.
