Believe me, everyone, letters and postcards work. Petitions are fine, but individual, letters or postcards influence pols as nothing else does. Each letter means more than one vote to them - it represents the sphere of influence the letter writer has.

Another benefit is that the reply you receive sometimes directs you to someone with more influence or direct responsibility for the subject of your letter/postcard.

One tip: let them know you are awaiting a prompt response. :)
