I've created a toll-free phone number, 1-844-USA-0234, that will dial all your members of Congress, no matter where you are.
Instead of having to look up 3+ phone numbers and call them separately, this single number will connect you to your representatives one after another.
The United States is a representative democracy. If there's a policy you'd like to see changed as a US citizen, ask your senators and representatives to act.
Calling Congress counts for a bit, and it's better than sitting around and complaining, or watching the news and feeling helpless.
When the phone is answered, you'll probably speak to a Staff Assistant who will listen to what you have to say. The office keeps track of how many people have positions on the issues, and these numbers influence policy positions.
Make sure to state what issue you're calling about and why. Also, you may want to provide your address to prove you're a constituent (and possibly receive a letter in return).
Good luck. The number 1-844-USA-0234 should be easy enough to save in your phone as "Congress". The next time you are sick of things being the way they are, give it a shot!
