Dawlish Neighbourhood Team are now proactively patrolling Seven Sisters to tackle reports of anti-social behaviour.
Then after the election, you won't see them again, not until the time when the next election comes around.
I don't think that the election has anything to do with it. Proper regular patrols should be effective. Once the ASB stops, patrols will be assigned elsewhere, and ASB there may come back. It is a continual problem.
