That scenario involves the possibility that Democrats actually take back the house in 2014 and senator Reid's failure to make meaningful filibuster reforms now, will still allow republicans to obstruct for the next 4 years, if the Democrats don't have 60 votes in the senate after the 2014 midterm election. We are already screwed for the first 2. The electorate may very well turn against the Republicans after watching more of their lunacy between now and the 2014 elections. But will they be discouraged enough to first give the Dems a 60 vote Democratic majority in the senate?
If Dems fail to get a 60 vote majority senate in 2014, than we will be obstructed for the next 4 years instead of just the first 2.
Senator Reid's failure to act strongly on filibuster reform, may have taken any chances we may have had for all of the next 4 years.
