Re:What to do (Score 1)

Really, the effect probably increases for a while, then decreases, then goes up as you reach closer to the full constituency of the official. However, if a group was to send a huge number of letters to an official, especially if they are not contituents, it becomes less effective than a small number of letters. This isn't for the same reason as the actual Laffer Curve, but rather because you upset the office staff of the politician. Believe it or not.
