The coverup is in progress.

AmericaBlog is reporting that every Republican senator voted against forming an independent, bipartisan investigation of what went wrong (except Vitter of Louisiana, who simply didn't vote, probably because voting in either direction would have generated significant backlash from either his constituents or his party).

Every Democrat (except Corzine of New Jersey, who also didn't vote at all) voted for it.

Those voting against can't claim to be representing their constituents — 76% of the public was in favor of such an investigation.

Hat tip to the Swing State Project, which has posted contact information for each of these senators, for people that want to ask them why they made the choice that they did.
