When the histories of the current 111th Congress are finally written, maybe it all will become clear.

For instance, why did House Republicans ever think it was a good idea to stake out a position on the payroll-tax issue that would leave them holding the bag for a new year's tax increase for 160 million workers? That has now been averted with Congress' passage Friday morning of a two-month extension of the current payroll-tax holiday.
