I thought about "Senator Golddigger Redux" . . .

. . . as my nickname for Claire McCaskill.

But it remains to be seen if she will be as ineffective and clueless as the orginal corpse-rider, Senator Golddigger.

So, given McCaskill's position as a slumlord for nursing homes in cruel, deplorable conditions, she shall henceforth be known as "Senator Ratchet."
