You have to marvel at Warren's timing:  He knew that once the valuation on a deal with Goldman would have been completely different after a federal bailout.  So he decided to bet on a bailout before it happened, but not before Paulson had announced that he was going to go for a federal bailout.

If Congress fails to approve the bailout, Mr. Buffett says, all bets
are off. His investment in Goldman will "get killed, and so will all
our other investments."

Now I am hoping, with Warren, that the bailout happens...
