I didn't vote in the recent Labour leadership election (er, either of them) as I don't feel sufficiently qualified to be a part of that decision. I was quite excited when Corbyn first became leader, but I've been rather disappointed since then. The repeated missing of open goals when he could have made major capital out of the government's cock-ups, dogged insistence on his old anti-capitalist anti-EU stance leading to an extremely lukewarm Labour contribution to the Remain campaign, continued dalliance with these SWP/StWC wankers, refusal to unequivocally condemn Assad or Putin, because that would make him a stooge of American imperialism, or something... it just goes on and on.
Labour needs a leader with solid social-democratic principles who isn't stuck in the past and has some clue what's going on in Europe, the Middle East and the wider world. Whether such a person exists, and has sufficient leadership ability and popularity to prevent the party from completely falling apart, I don't know.
