I just want to add that two of the strongest tools we had were our t-shirts and large decals on our vehicles. These attracted other supporters like magnets. I had complete strangers coming up to me to ask about Ron Paul. Those are the easy ones you don't need to persuade. Some would ask how they might be able to help and ended up being key to the campaign. Others had no idea there was an upcoming caucus and were relieved to receive the location, date and time.
I highly recommend bold gear :)
