Something which occurs to me as useful to know is senators and representatives whose states or districts have large numbers of scientists or companies which do large amounts of science or contracting. Some which occur to me:

I've missed many areas, please add to my list. Also, please work on adding to the list of states and congressional districts. I expect that every state and most congressional districts have at least one large employer which depends on science. It helps to have names and places.
