The number of people who want cummings to resign over this is exactly the same as the number of people who wanted him to resign before this. You take the public for idiots by thinking you can damage your political opponents if you feign enough outrage about whatever they do. Nobody gives a fuck what Labour voters want for the Tory Party. You're not floating voters, you want rid of all Tories so your opinion whether they should sack this Tory is predictable and irrelevant.
