This gives me a flashback to when statisticians found that the number one issue that predicted whether or not a Brit voted for Brexit was their opinion on the death penalty: https://www.bbc.com/news/magazine-36803544
Shortly before the EU Referendum, support for remaining commanded a similarly small majority but then lost. Those supporting Leave ran a more effective campaign, including making use of data gathered online, targeted advertising via Facebook, and mostly emotional arguments. So I would be very concerned if a referendum were to be held on capital punishment.
MPs of all parties are overwhelmingly against reintroduction and there is no chance of it passing in a free vote in the House of Commons.
Remain was nowhere near as dishonest as Leave, especially if you look at what the Electoral Commission said. Not to mention the two contradictory Leave campaigns.
I don't know who was saying it? I think everyone can agree (even the courts) that Leave campaigning was far more underhanded both in terms of veracity and in terms of legality.
> they're saying that Remain was worse
Worse in terms of less effective and less emotionally appealing, yes. Again that is fairly universally acknowledged.
