I think ascribing political ideas to a large brick and motor store shutting down a location or two is a convenient way for people to put their own spin on it. Large box office locations are moving out of cities all over the place. For reference, Toronto's worst neighborhood has an Audi/Benz dealership in it. They certainly experience theft/vandalism at higher rates than other dealerships but if they were to close it would be over a business decision rather than political motive.
Specifically to Portland - this article is stating that the police budget is back up to higher rates than it was in 2020, so if we're going to say defunding the police is contributing then it would have to be related to the 2021 budget decrease.

So what has significantly changed in the past 5 years in Wal Mart's ecospace? The prominence of online selling and reduction of store space. I think it's easier to explain that Wal Mart is shutting these locations down to accommodate for those shifts.
If you look at their annual report, they have been consistently decreasing their retail square feet metrics. Unfortunately we can't see what their inventory provision stats look like or shrinkage to see what $ of theft is happening.
