In fact, people don't "do something" because they estimate, rightly or wrongly, that they can't do anything that would make a difference. Millions worldwide protested the current US wars when they were getting started, but they went ahead on schedule. What, exactly, can citizens do to effectively influence their government anymore? If people perceive that rule of law is gone, the rational reaction is to "lie low" and hope to get thru these times unnoticed. Those still contacting congress may be old enough to remember a different USA and naive enough to not realize it is gone.
