I can see Labour splitting if Corbyn wins.
It will divide into real Labour and Tory lite. People seem to have a clamour for Labour roots, Labour values. The poor are being utterly left behind while wealth among a few sky rockets. One person owning as much wealth as someone needing to work for tens of thousands of years.
I think he will. Corbyn has shown himself unable to lead, Smith will struggle not to be better. Will he win the next election? Maybe not, but he will do less harm to Labour in the process.
Corbyn could lead if the dead weight and anti-labour were to vanish. All one has to do is spend twenty minutes looking at Labour MPs twitter accounts to see that Corbyn is a threat. Why? The old adage of follow the money. Much of the Labour Party is now cronies in waiting.
