B. Notwithstanding subsection A, the following provisions shall apply to the determination of the method of making party nominations. A party shall nominate its candidate for election for a General Assembly district where there is only one incumbent of that party for the district by the method designated by that incumbent, or absent any designation by him by the method of nomination determined by the party. A party shall nominate its candidates for election for a General Assembly district where there is more than one incumbent of that party for the district by a primary unless all the incumbents consent to a different method of nomination. A party, whose candidate at the immediately preceding election for a particular office other than the General Assembly (i) was nominated by a primary or filed for a primary but was not opposed and (ii) was elected at the general election, shall nominate a candidate for the next election for that office by a primary unless all incumbents of that party for that office consent to a different method. When, under any of the foregoing provisions, no incumbents offer as candidates for reelection to the same office, the method of nomination shall be determined by the political party.
For the purposes of this subsection, any officeholder who offers for reelection to the same office shall be deemed an incumbent notwithstanding that the district which he represents differs in part from that for which he offers for election.
