The Intrade prediction market has opened trading on whether "Sarah Palin [is] to be withdrawn as Republican VP nominee before 2008 presidential election." At 8:55 am, Tuesday morning, the market is selling the prediction at 18 a share. That means traders think there is an 18 percent chance that Palin will be removed from the ticket.

Intrade predicted Joe Biden would be Barack Obama's running mate in August and its traders were also correct about every Senate race in 2006. It fell flat in predicting a Democratic majority.
