... and why not? Like establishment Republicans everywhere, they have their safe seats, their lucrative sinecures, more than their fair share of the swag from Albany and DC, and no responsibility beyond making suitably harrumphing Republican noises every once in a while. Hardly the stuff of revolution.
As far as cultivating that 'potential' within orthodox communities goes, in the establishment Republican computer, the perceived effort may not justify the perceived results in any race they care about. The numbers are not that great.
Just by the numbers, the Orthodox and Russian Jewish communities can account for several hundred thousand votes within the state. In a competitive statewide race (including presidential electors every four years), that could be the difference. Problem is that so many of these statewide races have not been competitive, primarily because the establishment GOP leadership has seemingly taken a "dive" on them.
