I agree it will be an interesting watch to see how it beds in. It's difficult to see how he can succeed though as the press will be all over him, misrepresenting him and hounding him from the start. It's happened to 3 or 4 party leaders in recent times and none have really got past it.
For me the resignations that poured in after the result are in themselves no bad thing. Looking at the dismal performance of the other 3 candidates it's a pretty clear indication that the wider membership have rejected the Blairities and Brownites of the past couple of decades who were the choice of the parliamentary party. Of course the shady background manoeuvres that will already be taking place to ensure Corbyn fails are another matter.
