I would encourage STINGS on video and - where they have people identify themselves as Republicans and see if they refuse.
Even phone calls: Caller: Hi, I need help to register to vote, but am disabled. Will you help? A: Sure Caller: Does it matter that I am Republican? I cant stand Obama. Will you still help? A: FU Etc.
Get good tape and video. Set them up.
It would make for good local news.
Reporters are liberal, but they are lazy first.
Hand them a good news story with video, and they can’t resist.
Short, sweet.
Might want to be careful taping a phone conversation as it may be illegal in some states unless you have their consent.
