Call Graham's office even if you don't live in S.C. This affects EVERYBODY equally.
I phoned his Capitol Hill office yesterday and spoke with a courteous young man. I pointed out that he probably agreed with me himself, since I assumed that Graham hired only good Republicans. In the case of Graham, a "more in sorrow than in anger" approach may work best.
Always remember that these aides can be important people -- if not now, then someday. What they hear can also contribute to the mood of the office. It's always, always worthwhile to call.
