Just adding to the post below, I think what offices really hate are phone calls from The Left which they think have been organized somehow. The problem is...what does it mean to have been organized? If I post about an issue and suggest you call your member is that organization? If AARP runs a teevee ad? If MoveOn emails their list?
Obviously all of these are organized in some sense, but not in quite the same way. More than that, the offices don't ever seem to see angry constituents on the Right as being 'organized,' even when they clearly are.
