Monstrously depressing. Corbyn’s deranged worldview — which includes praise for all enemies of the West as well as (not so) thinly-veiled anti-Semitism (which I imagine he would insist is “just” anti-Zionism), his praise for Hamas and Hezbollah, his belief that Israel and the United States are central to all evil on this planet — does not appear to have done him any harm. In other words, either his supporters don’t care or more people than I had understood share this upside-down/day-is-night/ignorant-of-history view of things.
Julie Lenarz sums it up so well here.
