The news about Morrissey's toxic, idiotic political views hit the main UK media outlets (online and physical) on no fewer than 3 occasions in 6 months (late 2017 into mid 2018). By the time of the last one, his UK reputation had probably be damaged irreparably and permanently. He then announced a small UK summer tour to places he would usually have sold out pretty much straight away - the result? An embarrassing trickle of sales. Inevitably, the tour was cancelled. There is a big gap in the 2019 North American tour - the intention was clearly there for a UK/European tour but he appears to have bottled it. The results of this very poll say it all. It's only the die-hards who are left visiting this site these days and yet, even of them, around 50% completely disagree with his views, hence the crumbling of the fan-base.
Had he been someone like Tony Hadley, Phil Collins or Gary Barlow i.e. a renowned right wing voter, it wouldn't really have mattered. Huge numbers of people, however, were drawn to his world and the Smiths' due to the clear and passionate anti-right wing stance (Margaret on the Guillotine, Red Wedge, 'We won't vote Conservative', 'There are some bad people on the right' etc. These are the people that are now being driven away, and there are tons of them. Beyond the UK and Europe, it won't make much difference, as the main news organisations are simply not interested in him. People only really know him because of the music and the cultural significance of The Smiths.
