It's sort of a foregone conclusion that the Republicans are dying to spin this the Democrats' way.  I think the solution is to demand that any vote be dependent on McCain's support and the support of the majority of Republicans.  I cannot see how Pelosi or Reid could allow anything to move forward without those conditions fulfilled.

Bush will be in the unfortunate position of looking utterly incredible if he speaks to either regulatory failures or eceonomic structure.  He may, after all, be the least competent graduate of HBS in recent memory.  

The Democratic response must be forceful, pointing out the Bush administration agenda, and also coercive to those Congressional Republican leftovers from 2006...thay must admit their complicit behavior with regard to their utter failure to engage in any oversight whatsoever.

Remember in 2006? The dems gained control of both houses of congress. Pelosi emerged as a leader.
Everyone agreed that the war in Iraq was the issue.
Bush appointed a commission.

We wound up sending tens of thousands of more soldiers to Iraq.
The dems played dead.
Bush emerged as the strong one.

Neither Obama or McCain appear to have much to say about the economy right now. Bush is emerging as Presidential once again.
This is better news for McCain than for Obama - who has not shown himself to be a strong candidate thus far.
