This is so hard. I never like Tony Blair's brand of politics, and I can't like the Corbyn/McDonnell brand either.
Yes, I agree a shake up was needed, but not to the extent it's made, IMO, the party unelectable. Only by being elected into power will any future Labour Party ever be able to put its agenda into action. I'm convinced that what happened in Scotland, when the Labour Party was virtually wiped out, will happen here after the next election, though hopefully not to the same degree. And these voters will not turn to the Tories or the Lib Dems but to UKIP.
It was unimaginable a few years ago that Labour would lose nearly all it's Scottish seats. It only did so because the SNP offered an acceptable alternative to the Scottish voter.
But we've recently had, what I considered to be, an unacceptable President-Elect in the USA, and a swing to the far right across Europe. While Jeremy Corbyn doubtless appeals to some, he is not going to carry the popular vote.
The Labour Party still has a couple of years to reassert itself and find a leader who will bring back traditional Labour voters, and I'm not talking about the traditional voter being far-left, as I don't believe they are any more.
