Agree. Corbyn failed to appeal to cohorts of people on a number of issues. His position on Brexit made sense to the politically enlightened but to the average chap on the street it appeared indecisive. He irrefutably lacked credibility on the economy as seen by a huge jump in the markets.
Labour need to stop being so introspective and try to appeal beyond votes it's already won. You aren't going to make a dent into Tory seats and floating voters talking about nationalisation. I know this is unpopular on here but the Corbyn and Labour infatuation is not shared by the nation, demonstrably.
