Why especially since she's NDP? Because she's ~~far left~~ and that means affinity with "communist" (not really communist, but for the sake of argument, fine) China?
It seems like the CPC has been targeting Liberals more and potentially Conservatives as well. Their strategy if anything seems to be to inflame division between those groups. I'm not sure the NDP is really a focus of theirs from what we've seen, let alone especially so.
If anything I have more faith that Chow would not be influenced than other candidates whether knowingly or unintentionally. For one because I think she has strong principles but also also if anything her being born in Hong Kong and having connections there would I think more likely make her anti-CPC than pro and give her a stronger understanding of the CPC's unethical anti-democratic tactics.
And she knows that people will attack her for this kind of stuff and might be more on guard for it vs. other candidates.
Chow is not a "far left" tankie liable to have affinity for the CPC by any means, and I think she has strong personal integrity whatever you think of her politics and ideas.
Of course I'm making assumptions here too. We should probably stop making all these assumptions in this thread in general and some of the assumptions made are really unfounded. There's no reason to be assuming these things and fear mongering about Chow vs. other candidates.
