You make an excellent point. By paying up they were admitting they were wrong. Quite a feat for a lefty. Whether their brains processed it as such I don't know. However, enough repetitions of "I was wrong" may eventually have an effect, embarrassment if nothing else.

I think the proper approach is to keep making the bets, and pseudo-subtly start to encourage them to stay leftie. Maybe that will help them to see the link between "I lose money when I'm wrong" and "Leftie is wrong"...

Then again, their votes are tiny and they are probably not making a very effective statement for their causes anyway--so you might want to just keep them leftie for a constant revenue stream.
