Part of the challenge here is that Bambu is a Chinese company. Which means you would have to sue them in China, with predictable results.
You could try to sue them in e.g. the US, then use that victory to secure things like import bans, but that’s a very long, slow, and expensive process.
Yes, non-Republicans will vote in Republican primaries if the strategy is there.
My state is (now) firmly red. Whoever wins the Republican primary will almost certainly win the general. As such, voting for the least shitty Republican in the primary is far more useful than voting Democrat in the general. On top of that, at least my Democrat primaries have been very milquetoast. It doesn’t make much difference who wins that.
That all makes it a very simple decision to vote in the R primary.
