In the many discussions around Biden stepping down and potential replacements there comes Harris, and she is routinely touted as non-viable. Even outside of that particular discussion Harris seems to have always been held in low regard in both liberal and conservative camps since she came to prominence in the 2020 primaries.

Is it a particular failing of mine that I don't really understand why this is the case, or is it only people who regularly pay attention to politics that think this, and most of the electorate knows almost nothing about Harris one way or another?

A quick search found a few articles in the New Yorker and Atlantic, but those are paywalled, so I was left with what seems to be the kindest interpretation of Harris I've ever seen invoked: https://washingtonmonthly.com/2021/06/10/why-they-hate-kamala-harris/ and another that seems more even-keeled and views her as simply a politician getting crap for handling problems so they backfire on her instead of Biden: https://www.bbc.com/news/world-us-canada-60061473

These don't seem like the kind of thing the greater electorate cares about though, true of many political issues to be sure, but so far it seems more like a feedback loop of dislike that no one bothered to interrupt rather than any major failings on Harris' part?

Didn't find anything crazy in a quick review of her Wikipedia article, not a source of truth, but if there were something egregious I would expect some mention of it.

Is it something unique to her home state of California and them being a large section of the population online is driving this?
