Also, I disagree not just with her salty attitude towards people like AOC, I disagree with her premise that there needs to be different Democrats for different states. As has been said on here by multiple people, given the choice between a Republican and a Democrat that is trying to lean conservative on some issues, voters will go for the genuine article nearly every time. And the progressive Democratic platform already has plenty of appeal for all Americans (except maybe the uber-rich): raising the minimum wage to a livable amount, giving everyone equitable access to healthcare, improving infrastructure, improving education standards and school infrastructure, cleaning up the environment, the list can go on for a while. Show me a moderate Democrat and I'll show you someone that will vote for a Republican in a heartbeat given a half a reason. The focus should not be on trying to target an ultra-specific subset of voters, it should be trying to demonstrate that a modern, progressive, fully-adopted Democratic platform can improve all American lives, regardless if you believe that gay marriage or abortion should be legal/illegal.
TL;DR: moderate Democrats are just as bad a parasite on American politics as Republicans so long as they go out of their way to cause divides in the Democratic Party. If you want to be Republicans so badly, go be Republicans.
