Who makes the final call regarding redistricting? If it needs to pass in those two chambers it might not work out for Repubs.
On edit, I looked it up and wikipedia says this:
The New Jersey Redistricting Commission is a constitutional body of the government of New Jersey. Like Arizona, Idaho, Hawaii, Montana, and Washington; the redistricting is completed within an independent, bipartisan commission. The apportionment of members of the Redistricting Commission is carefully balanced between legislative and executive majorities and is purposefully titled to allow the minority party an equal amount of seats on the commission.
New Jersey Congressional Districts. Note that in the 2008 elections, Democrat John Adler picked up the 3rd district from a retiring Republican.
“ 1. (a) After each federal census taken in a year ending in zero, the Congressional districts shall be established by the New Jersey Redistricting Commission.
The commission shall consist of 13 members, none of whom shall be a member or employee of the Congress of the United States. The members of the commission shall be appointed with due consideration to geographic, ethnic and racial diversity and in the manner provided herein.
(b) There shall first be appointed 12 members as follows:
(1) two members to be appointed by the President of the Senate;
(2) two members to be appointed by the Speaker of the General Assembly;
(3) two members to be appointed by the minority leader of the Senate;
(4) two members to be appointed by the minority leader of the General Assembly; and
(5) four members, two to be appointed by the chairman of the State committee of the political party whose candidate for the office of Governor received the largest number of votes at the most recent gubernatorial election and two to be appointed by the chairman of the State committee of the political party whose candidate for the office of Governor received the next largest number of votes in that election.
Appointments to the commission under this subparagraph shall be made on or before June 15 of each year ending in one and shall be certified by the respective appointing officials to the Secretary of State on or before July 1 of that year.
Each partisan delegation so appointed shall appoint one of its members as its chairman who shall have authority to make such certifications and to perform such other tasks as the members of that delegation shall reasonably require.
(c) There shall then be appointed one member, to serve as an independent member, who shall have been for the preceding five years a resident of this State, but who shall not during that period have held public or party office in this State.
The independent member shall be appointed upon the vote of at least seven of the previously appointed members of the commission on or before.
