The days are coming, and are arguably already here, when it will be as bizarre to question the present Government's (and even more so, last year's) old links to the 1980s Far Right, and thus to Thomas Mair, as it would now be to question the Bushes' and the Clintons' links to Saudi Arabia, and thus to the attackers on 11th September 2001.
We, I, used to branded as loonies for mentioning that, too. But everyone accepts it now, and a lot of people pretend that they always did.
That does not mean that the Bushes and the Clintons organised those attacks. Nor that, say, Michael Gove or Liam Fox ordered the murder of Jo Cox.
But it is still important, and it raises very serious questions about fitness to govern.
