GAW: sorry, I sometimes have a “long writing style”. Hope I didn’t bore you.
The short answer is that for the people that need the pool and have been doing so for years, it’s REALLY important; perhaps for medical reasons for some of them. And not much political clout is needed to petition Dov Hikind. I don’t think any local Williamsburg politicians or organizations were involved. (Williamsburg does not have frum politicians, so contacting Hikind who would likely be more understanding was logical.) And it’s the media that made a big fuss about this, it wasn’t such a big deal.
