Do I get a Negative Feedback if I run up the bidding and DON'T PAY???
Yes but what the heck, it would be worth a negative. If you do it, just be sure you wait a few days before you leave the neg. If you leave it right after the auction ends, its called bidding just to leave neg feedback and they will remove the neg from their profile and suspend you.
You don't have to worry about that. The e-bay listing specifically states that Cindy will refuse to speak to Republican groups. Go ahead and win the auction, and then demand that she come and speak to a conservative group. She has already said that she will refuse to do so. Therefore, you can bid with confidence.
