Paul Mason reprises a Remoanian whine in the Guardian today; they may have lost the vote, our Article 50 letter is good to go, our negotiating teams are primed but still he clutches at the most feeble of straws. Demonstrations matter, he says, because they lay the ground for future electoral victories. Thus NHS and pro-EU protesters will see no easy victory now, but will score unexpected wins in the future. To a point, Lord Copper. Was the Brexit vote then a delayed effect of the Countryside march, the first I ever attended? It was as much a protest about the disregard of the elite Metropolis for the rurality as about hunting, and until the Iraq march was the biggest ever seen in London, dwarfing the recent piddling little NHS and pro-EU huddles. And what of the anti-Blair march, the second of my lifetime (and probably the last)? Did the size and scale of this presage the overwhelming destruction of the Labour Party, it's utter unelectability for all time? Yes, the pendulum will swing back again. It always does. But not because of enfeebled radicals such as Mason calling fewer and fewer ageing followers onto the streets. Generational change will drive a future political rebalance. Demonstrations are really no more influential than a successful pop song or blockbuster TV series. It's universal suffrage and the secret ballot that really bring change – both of them striking fear into the hearts of the Illiberals.
