"Mr. Corbyn’s triumph isn’t that surprising":
Labour’s Dead Center, by Paul Krugman, Commentary, NY Times: Jeremy Corbyn, a long-time leftist dissident, has won a stunning victory in the contest for leadership of Britain’s Labour Party. Political pundits say that this means doom for Labour’s electoral prospects; they could be right, although I’m not the only person wondering why commentators who completely failed to predict the Corbyn phenomenon have so much confidence in their analyses...
But I won’t ... get into that game. What I want to do instead is talk about one crucial piece of background to the Corbyn surge — the implosion of Labour’s moderates. On economic policy, in particular, the striking thing ... was that every candidate other than Mr. Corbyn essentially supported the Conservative government’s austerity policies.
Worse, they all implicitly accepted the bogus justification for those policies, in effect pleading guilty to policy crimes that Labour did not ... commit. If you want a U.S. analogy, it’s as if all the leading candidates for the Democratic nomination in 2004 had gone around declaring, “We were weak on national security, and 9/11 was our fault.” Would we have been surprised if Democratic primary voters had turned to a candidate who rejected that canard, whatever other views he or she held?
In the British case, the false accusations against Labour involve ... claims that the Labour governments that ruled Britain from 1997 to 2010 spent far beyond their means, creating a ... debt crisis that..., in turn, supposedly left no alternative to severe cuts in spending, especially spending that helps the poor.
These claims have ... echoed by almost all British news media ... as facts. It has been an amazing thing to watch —... every piece of this conventional narrative is ... nonsense. ... And all of Mr. Corbyn’s rivals for Labour leadership bought fully into that conventional nonsense, in effect accepting the Conservative case that their party did a terrible job of managing the economy, which simply isn’t true. So as I said, Mr. Corbyn’s triumph isn’t that surprising given the determination of moderate Labour politicians to accept false claims about past malfeasance.
This still leaves the question of why Labour’s moderates have been so hapless.... Labour’s political establishment seems to lack all conviction, for reasons I don’t fully understand. And this means that the Corbyn upset isn’t about a sudden left turn on the part of Labour supporters. It’s mainly about the strange, sad moral and intellectual collapse of Labour moderates.
