A law proposal is on the docket to expand the municipal borders of Jerusalem. The issues involved are complicated with the various towns affected not losing their local influence while becoming  part of Greater Jerusalem - voting for local leadership and for city leadership. Budgets and I am sure many other issues will be affected and have to be worked out.

Or maybe not.

The heads of the Haredi parties have expressed their dissatisfaction with this proposal and have said they would oppose it when it comes up. (source: Kikar)

Why?

Because they are concerned that with all these new areas being included to expand Jerusalem, many more secular and dati residents will be added to the city registrar and will make it that much more difficult for a Haredi to be elected as mayor at some as of now unknown point in the future.

The original proposal might have been based on gerrymandering, and it might not have. I did not hear any such claim, in favor or in opposition, about the proposal. The opposition to it is definitely dabbling in gerrymandering.

Chazal say that in the days of Mashiach Jerusalem's borders will expand - some say they will encompass everything known today as Israel (and Israel will expand further), while others say different measurements, including the distance a horse can run in half a day. Basically, I guess this shows we are not yet in the days of Mashiach...
