He‘s seen as the mastermind behind Vote Leave and Boris’s 80 seat majority. I’m now thinking that Boris really sees him as crucial and thinks with it being so early in the electoral cycle he can ride this out and it will be forgotten by the time we go to the polls, which is probably correct.
As for Cummings, he has a burning ambition to revolutionise British politics. He’s been close to the top table of power a couple of times but has been foiled each time, most notably when Cameron told Gove that if was to serve in his cabinet then Cummings would have to go as his top aide because he’s a ‘career psychopath’. Now he’s made it he’s not going to go easily.
Personally I’ve always thought he won’t last because by all accounts he’s completely intransigent, arrogant, aggressive and not interested in diplomacy. He’s kind of like ISIS in that he‘s made too many enemies not to be destroyed.
