I don't know if McCain is actually holding things up. This must infuriate Reid and Pelosi. They dislike McCain deeply, (Reid has made it personal) but are too afraid to move ahead without his cover. If they don't move ahead, and the markets crump--they are to blame. If they do move ahead and the Amrican public rebels against the costs and the giveaways of this package, their party will be punshed at the ballot box. They are in a bad spot, and (hopefully) McCain will use his available leverage to improve the bill (reducing taxpayer liabilities as much as possible and keeping the bill focused on the problem). If so, he'll be able to rightfully hold this out as an improvement he's responsible for.
