I'm a resident of a leftist enclave in the US, and that's what "the left" refers to, unless you have a better definition? I'm not sure what your complaint was, I've been very specific about the groups I'm talking about, but I still have not idea what you consider "the left" to be. If there isn't a distinction between liberal and "the leftl in your view then we have been talking past each other. Liberals haven't turned away from Ukraine, they have supported Ukraine, there's a clear distinction. But the left in the US is aligned with Trump on this matter, and there's also a lot of crossover from the left to Trump in the form of Tulsi Gabbard and RFK Jr, who both get a lot of yard signs in my town from houses that were "leftist" a mere year ago.

I think the issue is you're using terms like "the left" and "a lot" but you're talking about a very niche, fringe set of the population as if it represented any significant proportion. I would not say that the non-conservative kook vote is synonymous with "the left" but at least I can understand your point a bit better.
