Maybe so. And he wouldn't be alone.
Here's the headline which prompts such thinking: Steinbrueck to "stop at nothing" to stop new viaduct. Bold words.
And I am not at all surprised at this twist and have been predicting it; the issue of a new Viaduct — the Rebuild — is explosive. I believe that Steinbrueck is making no idle threat. He is quite committed; I have a strong sense that he would be willing to be arrested in peaceful non-violent civil disobedience. Chaining oneself to a bulldozer and so forth. Such discord is a very real threat to the Democratic hegemony in Washington State because it makes many of the elected Democrats look like blundering incompetents — which unfortunately is all too true; it also has troubling implications for the Presidential election in '08.
Conversely, some sort of "Repair & Prepare" would satisfy Steinbrueck, his fans and allies, and also save the bacon of Governor Chris Gregoire, Speaker Frank Chopp and other electeds who will be happy to be out of a jam and will throw their support to Peter in his future endeavors. It is the grand compromise which will save the day.
Peter will be Mayor if he can pull this compromise off. And I think he has a very strong hand. Just about every other Democrat (a few such as Chopp, Dickerson, Somers, Licata excepted) have been dream-walking. They need help. Repair & Prepare is the route out of the mess and Peter Steinbrueck is a civic figure of sufficient stature around which a coalition can gather.
