To answer Kevin's question, apparently Arlen Specter was not able to reach Chuck Grassley on the phone to admonish him for saying that health care reform means the government decides whether or not to pull the plug on Granny. The two of them are duking it out on Twitter instead. (Grassley's latest: "So change ur last Tweet Arlen.") I wonder if the increasing numbers of senators on Twitter finally spells the end of the Senate's famed (and often feigned) comity? You can't very well be liberally referring to "my friend, the Senator from Pennsylvania" when it uses up a whole 101 characters.
