Jeremy Corbyn looks set to win with the support of 43% of members and most of the constituency branches. Corbyn represents the hard left of the party. His anti-austerity and pro-social democracy platform has been very well received by grassroots members and could prove useful in preventing any further bleeding out of votes to the Greens. Although, he would risk losing the centrist vote to the Liberals and Conservatives permanently due to his hardline proposals.
Liz Kendall, another hopeful, is by far the most dangerous to the Tories. She is largely consider to be the Blairite candidate of this race with her center to center-left approach. Kendall, however, looks like a non starter with barely 6% support within the party.
Who am I backing? Corbyn all the way! Corbyn will effectively give the next election to Tories.
