The dems should stop talking about extending tax cuts and let the act expire, just like it was written by the cons to do. Forget about it. Stop talking about it. Let it die.
Rather, introduce a bill that would cut the tax rate from whatever the rate will revert back to, to the current - or lower - rate on all incomes lower than $250,000. Call it the Obama tax cut.
Let the obstructionist party vote against that.
