I am strongly recommending Rebecca Long-Bailey with no second preference and Richard Burgon with Dawn Butler as 2nd preference. Firstly their voting records in parliament put the other candidates to shame. Secondly I believe they represent the best electoral chance for Labour with radical policies to reverse the endless damage done by austerity, neo liberalism and global warming (and they're not southern remainers, increasing the chance to win back the leave voters), when Labour went for it and didn't try to appease the remainers and Blairites they nearly snatched the election inspite of them. In 2019 we lost because of the rights persistent undermining of the Corbyn and his supporters, they spent 4 years scheming and spewing out crap about Corbyn and failed to spend anytime trying to beat the Tories, then they (with Starmer as lead advocate) reversed Labour's policy of respecting the referendum result and push for a deal that won't harm working class people, to a call for a second referendum that was always going to lead to defeat in the election. They basically told half the population that a democratic promise means nothing. In the end instead of mitigating Brexit to make something good of it we are at the mercy of some right nasty characters who have no interest in the needs of working class people. Thirdly look at the two faced schemers*and back stabbers that support the other candidates (both Nandy and Starmer were coup participants) as well as the big financial backers.
Finally and most importantly I believe a victory for any of the others will signal the end of the project to attempt to try and dramatically change the direction of Britain (and the world). An end to Labours plans to redress the massive imbalances in our society. A victory for Starmer and Nandy (both talk left and of unity in the same way Owen Smith did) will mean a return to the Labour Party that shed principles faster than it could drop bombs on the middle east and academize our schools.
I'm just burying my head in the Sanders campaign now.
The audience for the Sky Labour Leadership debate voted a Nandy landslide.
Still, I am sure the Leftwaffe know best.
