Firstly, a 'supermajority' isn't a thing here. You are just talking about a very big majority. Supermajority has a different and specific meaning.
And while everyone should vote as they want, assuming that Labour will get a huge majority feels a bit brexit-vote like. However one feels about Starmer and where he has taken labour, they are the only option to ensure we don't have the tories in power any longer and being complacent that that will happen is a risk. IMO.
