Building on @Darin's answer the post linked above provides the code needed to display the 'why' message.

 foreach (var obj in ModelState.Values)
            {
                foreach (var error in obj.Errors)
                {
                    if (!string.IsNullOrEmpty(error.ErrorMessage))
                        System.Diagnostics.Debug.WriteLine("ERROR WHY = " + error.ErrorMessage);
                }
            }
