he calls about anything he feels they should know about. You would be amazed at how easily you can get through to talk to them. If they are not there, their aide will take a message and you either get a phone call back or a letter.
In Michigan we have Carl Levin, Debby Stabenow, and Vern Ehlers. Their aides and my husband are on a first name basis. Literally. The aides are the front line of the reps and sens etc. They DO make note and you DO get a letter in the mail about your phone call. It doesn't really change anything, but at least the elected officials are aware of what the temprament of the voting public is.
