All of the groups mentioned in your quote from the article are opposing AOC because of her stance on Palestine not being strong enough. It has nothing to do with her “not being maoist enough”.
A ceasefire in Gaza is extremely popular among the electorate, so this stance is pretty solid according to your “flock to progressive ideals” argument. Linking to the wikipedia page on Maoism to make your point here makes absolutely no sense. Especially considering the liberation maoists are stated as being “a much smaller maoist caucus [within the DSA]” right there.
If you want to make an argument that there should be no hesitation in endorsing her despite her support for the iron dome and support for Biden/Harris with them “working tirelessly” behind the scenes on a ceasefire, be my guest.
Big money donors did not swing from Democrats to Republicans, this is a flawed analysis. The uptick in republican top 40 funding came from existing republican funders greatly increasing their funding levels and a large part elon musk dumping half a billion into Republican hands.
None of that is Democrat funders switching sides as you are suggesting. And it is not even clear to me if democrat funders gave less this go around adjusting for inflation. It seems Soros didn’t give money to the DNC but he instead funded democratic organizations in different ways.
Votes being prioritized more than dollars makes no sense whatsoever considering dollars are a major way to secure votes.
