In addition to writing ABOUT math, there is are great opportunities for mathematicians to write about federal (and other) laws and policies that affect us. For good example, please see: https://risestronger.org/newsroom/op-ed-fy18-october

If anyone out there would like to write one of these, please feel free to contact me for advice/help; I am the Director of Government Relations for the AMS and you can find me at kxs@ams.org

The link given above — AMS Communicating Mathematics in the Media: A Guide — has many good examples of op-eds written by mathematicians. Here are two more, recent pieces, that are focused on using mathematics in the policy arena:
