Bloomington borders Minneapolis to the south and is home to the airport and mall of america, which is an important source of all kinds of tax revenue. It was 74% white as of the 2010 census and is likely to be less white when the 2020 census #s are fully published. There are wealthier and more white suburbs to the west. Tobacco shops in minnesota are almost exclusively associated with lower income neighborhoods. these are essentially bodegas in most of the twin cities (an anecdotal observation on my part).
There are likely a few things going on here. A perceived changing of community demographics and stereotyped clientele associated with vaping retailers, legit smoking health concerns, and suburban culture war fears being put into policy at the city level. The Bloomington city council, as has been the case in several communities, have been taking steps to address inequity (including inequitable health outcomes) after facing increasing pressure to do so. I suspect this is all part of that (likely) box-checking exercise. In the same city council meeting they also banned conversion therapy practices but the tobacco thing is getting all of the press. A mosque in bloomington has been attacked multiple times including a bombing plot, the TCs are at the epicenter of racial and economic inequity that's fueling media and culture warriors, and the protests and white supremacist attacks over the past year have led to gov't types feeling the need to "do something."
Whether or not this is all pointless, virtue signaling, government overreach, or whatever label that's being applied to it the 4 council members who voted for it (out of 6) almost certainly did so because their constituents supported the idea. These people are not willy-nilly making these choices and they're too small and insignificant to be part of some major lobbying campaign on conspiracy. These are people who likely believe they are doing something positive or useful that their suburban "won't somebody think of the children constituents" want. Is everybody involved here stupid or short-sighted - maybe, but if the people don't want these things they'll replace the council members and change the ordinances. Minnesotans vote at a higher rate than the rest of the country and voting is the perfect exercise to meet the demands of their passive aggressive, MN nice, Lutheran shunning culture.
