McCain's already on record as supporting the bill the Senate is scheduled to take up tonight.  (If Obama has also said he's voting yes, please feel free to disregard the rest of this post.  I haven't heard news to that effect.)  Suppose he votes no, calling for Congress to remain in session until the crisis is resolved--so it can act readily if there are indications the real economy is starting to be seriously harmed.

It's had a bunch of tax cuts added to it.  So Obama could say, look, this is worse than the House bill that was voted down, moving in the wrong direction as far as addressing the crisis, Main Street and the taxpayers are concerned.

He also could truthfully say that it is clear from the public reaction that a great many citizens and taxpayers--and a growing number of Wall Street insiders and economists with expertise who are now coming forward--have real concerns about whether this is the best available alternative to protect Main Street and the taxpayers while most effectively resolving the situation.  

He recommends (better still if he could announce this, with Pelosi and Reid at his side) that Congress hold joint, nationally televised hearings, beginning tomorrow, at which top economists say what they think and field any and all questions.  This should provide greater reassurance for members of the public who have concerns or fears.  Meanwhile, Congress will remain in town, so it can vote on very short notice if need be, until the situation is addressed.  

Just putting this out there to see what folks think.
