If the committee resists, Worsh will use the 'no atheists in foxholes' approach: let the market crash, then they'll come around. Near-term, that means pain in all markets—stocks down, bonds down, dollar not up. That's the Fed's worst nightmare.
We saw this with the TARP vote: it failed, the market crashed, then everyone got religion and passed it. If Worsh can't get the committee on board, he'll let the market force them.
