Sounds like you are in a marginal seat!
I struggle with the idea that elections have a higher profile and more voter/candidate engagement in a marginal seat.
I live in a marginal seat in which all three main parties are or have been in contention in recent years. I live in what has historically been a marginal ward in which Labour, Lib Dem, Conservative and independent candidates have all been elected.
In 33 years, in all the local, national and European elections, I have had just three canvassers or candidates knock on my door. So I don't take seriously the idea that there is meaningful engagement with voters.
I get leaflets through the letterbox, but that's a one-way conversation in which the parties tell me what they want to tell me and I don't get to ask questions. At previous elections up to 2017 there used to be hustings, but in 2019 the Conservative candidate declined to attend a hustings in this part of the constituency, ostensibly because the organisers were suspected of being hostile lefties so it got cancelled. No-one has been prepared to organise one this time round.
What passes for campaigning is controlled by the parties and the broadcasters, who decide what issues they think are important and who shy away from engagement with anyone who might ask awkward questions.
I have now cast my postal vote, having received two Labour leaflets, one from Reform but nothing from the outgoing Conservative MP or any of the other candidates.
