I understand how this would be infuriating to other locals. But it shows the power of community organization. They don’t win because America is systemically pro Hasidic, they simply turned out the vote (after years of non-participation.). This is an encouragement to be active in your own community. If you don’t, someone else may do it for you.
The cult leaders tell them how to vote and then bus them to the polling station. They also largely are unemployed or work for others in the cult, so there is no obstacle there.
It's a scientology level cult, not a "community", and while certainly impressive knowledge and coordination to hijack tax payer money, it's still nakedly fraudulent.
