I'm quite glad he has won, it will mean real opposition and a change in the political direction as the Tories will have to dive left on some issues to clamber for the centre ground.
But he is going to be in for a hard time and it won't be the right wing that will give him the biggest kicking IMO, he has already talked about housing and rent controls being a big issue, that will alienate a lot of the champaign socialists and wealthier labour supporters who want equality as long as it doesn't affect house prices, and then you have his yet unqualified stance on immigration, labour lost lots of votes from the working class on this issue, now the calls of racists Yada Yada is warranted and also misguided you have to listen to and address these issues properly, throwing numbers and stats around doesn't work (as has been proven at the last GE)
His anti nuclear approach scares me as we need independence in this area , and his stance on Argentina is a little off, but as a neutral in this dog fight I am glad he won.
I have to say though that I do find it interesting that within social media he is applauded for being principled and yet those that have stood down today are derided as a little contradictory. I also think it's slightly presumptions that all those disaffected/can't be arsed voters are all part of some left wing sleeper cells.
It's going to be interesting for the next couple of years and I expect that there will be a lot of talk of 'propaganda' and right wing press when he comes under scrutiny, which as opposition leader you should expect, yet I think a lot is going to come from within his sphere and they are the ones to watch out for.
Bit of a rant
