That's because people just vote once every few years on election day.

Vigilance includes actively following politics (not just the sensational BS headlines in TV news and newspapers, but the real deal), marching and demonstrating when needed, participating in your preferred party and making sure the right people get its nomination, and so on.

Don't just "write your congressman" about issues, for they could not care less. Write online, influence others, organize, and make them care (whatever your politics, this is just so the politics are closer to what people want, not so that the politics are "the right politics", which doesn't exist).
