What if Congress were to quickly pass the existing legislation or, alternatively, just let it drop? How would voters react? This topic was the subject of a lot of discussion over the past week, from voices such as Megan McArdle and (since I filed the column) from Nate Silver and Jonathan Chait. Looking forward, we are on much more shaky and speculative ground but I find Chait most persuasive in arguing that the rationale for Democrats to move forward and pass the bill is that they've already voted for it and thus "already own the downside." They will be attacked for "having voted for tax hikes and Medicare cuts and death panels" regardless of the outcome.
