He has massively narrowed the gap with the conservatives, convinced double the number of labour voters to vote ‘remain’ in the EU compared to conservative voters (see http://lordashcroftpolls.com/2016/06/how-the-united-kingdom-voted-and-why/) and has invigorated the Labour party with hundreds of thousands of fresh members. But all you see is failures based on what concrete evidence?
