Automated dialer's are evil, and only make you look bad.  If I happen to pick up the phone without checking the caller ID, and then get dead air because you use an automated dialer... you better hope that I don't check my caller ID after the fact because it might be costing you a vote.  Also along the lines of bad advertising are automated messages.  I'm going to vote for a person, not a message.  I'm going to vote for a person, not a robot.  Every time you use one of those automated systems and make yourself look more like a robot, and less like a person, the less likely you are to get my vote.

Candidate beware.
