Sarah Palin, John Edwards and the Way We Choose our Vice Presidents

The vetting process for vice presidential candidates is clearly quite different than that for the people on the top of the ticket. Vice presidential candidates must face a series of, presumably, difficult interviews from the nominee's team and provide information on their background to the candidate, but that is about it. Not only is there no way of knowing whether or not the vice presidential nominee is being entirely forthcoming, but the vice presidential candidate does not have to face any test from voters or the media until she, or he, is already on the ticket.
