It's not rocket science: Calls are what all the congresspeople pay attention to.
1. best is to have face-to-face- townhall?, go to them, and local offices. If in DC find way to an event of theirs. ask questions, push for answers.
2. absolute most important thing that people should be doing every day is calling.
***You should make 6 calls a day (yup. SIX)***:
2 each (DC office and your local office) to your 2 Senators & your 1 Representative.
