Ignore the “phone-y” townhall meetings and show up on their front lawns. Bring posters and banners, notify the media.
It would be a good idea to organize “citizen’s townhall meetings.” Invite the congresscritters and the media, then make a point of how our “representatives” won’t show up to answer their constituents.
Bring posters with pitchforks and torches on them.
Bring tar and feathers and an effigy of the congressbastard in question.
