Ron Paul gave an impromptu speech at the Phoenix Airport on June 16th 2007. He answers questions from the group of supporters there. I think this could be something you can pass around to friends and family members to introduce them to Ron Paul. He talks about illegal immigration, health care, a 9-11 investigation, the environment, alternative fuels and more!
This is probably the best speech I have seen in terms of the variety of questions he was asked and able to answer.
If you still haven't donated to Ron Paul's campaign you can do that here.
