A fairly cheap and easy way to have a direct impact.

1) Identify, and gather the names of their residential neighbors.
The people who live near their home, in-state.

2) Get a smallish group (10-30 people) to meet up write short cogent complaint messages about financial misdeeds (voted for), etc.
A different message from each sender.

3) Send each neighbor a couple of personalized postcards; expressing disgust in their neighbors political behavior.

• Do not criticize wife's, children, "husband's" etc. This will give them ammo to villanize the message.

Let the formerly friendly waves, shift to withering eye-contact avoidance.
Let their wife's and children talk about it.

Shame from their neighbors.
