Dont waste money running a straw poll. They're dubious enough when they're run by the party. Running them on behalf of a candidate is the bottom of the credibility barrel. Instead of running a straw poll, invest in something gimmicky to attract people to your booth. You know what works? Models. Hot, twentysomething women in tight Ron Paul t-shirts. They cost $100 a day and they attract people to booths better than free booze.
