A few weeks ago I posted that the polls show Corbyn in the leader, but I didn't believe that the party would be stupid enough to go through with it. It now looks like I was wrong and Labour is in a kamikazi mood.
We now have to consider what would happen if he won. I previously pondered that he would step down immediately, now I don't think so and he will try to oppose. How that will be done though, I don't know.
There are some challenges. Firstly, Corbyn has said that he will pick his own shadow cabinet after previously saying that he would bring back shadow cabinet elections. He actually gave his Labour opponents a good idea for ruining his leadership with his earlier plan. There may be movements to bring back shadow cabinet elections before the leader is announced on the 12th. If many moderates stand in this election and have to be appointed to the shadow cabinet they can make it pretty impossible for Corbyn to effectively oppose. There will be splits in the shadow cabinet on a daily basis.
Maybe Jeremy Corbyn will get to appoint his own people, but with so few supporters amongst his own MPs would he be able to fill enough posts? And will these people, who are a permanent awkward squad, be able to show loyalty to their leader? They've never been able to do it before!
Even if Corbyn gets a shadow cabinet, how on earth can he command a majority of his own MPs for the parliamentary votes. David Cameron and George Osborne will bring forward votes on lots of policies which moderate Labour MPs agree with. It will be like two cats playing with a mouse.
Let's say that the majority of moderates stay silent and go along with Corbyn's votes for the most part. What happens when the polls and elections show Corbyn to be a loser (as they surely will)? Will they still keep their counsel?
Meanwhile, and you can guarantee this, the Tories will bring up every past dubious association that Corbyn has shown in the past 30 years. We've had a taster the last few weeks with some stories of dubious appearances to some extremists, I'm pretty sure that it's the tip of the iceberg.
Also, there's been some fleeting shows of Corbyn's hot temper. Given some tough questioning by our more difficult interviewers it's clear that he will lose his rag. How will this come across?
There are also questions about what the other moderates will do? Will there be a split? Probably not. They will easily be able to get enough signatures to trigger a new election, but will they want to against a big democratic mandate for Corbyn? Will they stay to agitate while waiting for Corbyn to crash and burn?
This is definitely the most interesting period of politics for the last thirty years, and I haven't even starting talking about Corbyn's crackpot policies. Let's tackle them if and when he becomes leader.
It's so gripping.
