The 203-222 defeat of the measure to ban the "Slaughter rule" might be a more positive sign for opponents of the Senate bill than many realize. If opponents can keep together all the Democrats who voted to ban this rule and still have the remaining Democrats who are listed as firm "no" votes by FDL, the Senate bill would be dead in the House.
UPDATE: Michael Barone has more analysis of the dynamics of this vote. See also Malkin.
