While the Hard Left's is not the only possible way of interpreting the facts about Latin America, for decades the Hard Left has been the only section of British politics to have bothered to learn those facts.
In its greatest ever triumph, it has elected and reelected as Leader of the Labour Party one of its own most accomplished experts on the subject.
Between them, Jeremy Corbyn's and Chris Williamson's knowledge of that rapidly rising continent is approaching the encyclopedic.
Their enemies within and beyond the Labour Party may wish to question their analysis. But they cannot do so, because they have chosen to remain perfectly ignorant of the data to be analysed. So all that they can do is scream abuse.
Alas, those abusive screamers predominate within both main parties on the floor of the House of Commons, where they also seem to provide all of the Liberal Democrats, all of the Scottish Nationalists, and all of the Democratic Unionists.
Another hung Parliament is coming, however, and we need our people to hold the balance of power in it.
It has become a local commonplace that I am on 30-30-30 with Labour and the Conservatives here at North West Durham, so that any one of us could be the First Past the Post.
I will stand for this seat, if I can raise the £10,000 necessary to mount a serious campaign. Please email firstname.lastname@example.org. Very many thanks.
