I presume you are saying that with the emergence of current Orthodox Jewish and "Russian Jewish" children into voting adults, we will see some local pockets of Republican power within NYC going forth into the future.
But that presumes that (1) these current children will continue to hold to the more conservative political views of their parents into the future, and not be influenced too much by college leftists and (2) these current children will remain in these pockets and not dilute their potential voting power by scattering around the country or to Israel.
So only time will tell.
Some numbers indicate that they vote republican (not necessarily conservative) at barely above 50% which is good, but an indicator that they are at best moderate republicans.
