So I was thinking that maybe modifying our strategy a bit might be worth examining. I love the postcards (obviously) but I was thinking of using a tactic right out out the "progressive" playbook. How about switching to pre-printed letters & envelopes? I believe that each letter gets a response doesn't it? The automated replies that you get via. email are too easy for them to just brush us off.

Rules for Radicals
Saul Alinsky

RULE 4: “Make the enemy live up to its own book of rules.” If the rule is that every letter gets a reply, send 30,000 letters. You can kill them with this because no one can possibly obey all of their own rules.

Just a thought.
