Back when the markets were riding high and the Bush people could boast about their portfolios, Republicans recommended that the best answer to Democrat protests was GOTV. Now that Democrats have worked hard to GOTV they consider it voter fraud. You cannot have it both ways.
Congress knows it can arrest Rove. But they don't want to stir things up, at least not yet. Congress also knows a debate on US foreign policy is not taking place. But in a democracy it is sometimes necessary to let things get so bad that there is an emergency. What will the US do for instance when the cost of import triples? Or when meney market funds start losing value because they are full of defaulted money market instruments that are not guaranteed by the FDIC? The time will come when the non-government government will be washed down the drain.
