Danny Lineberry, spokesman for House Speaker Jim Black, D-Mecklenburg, said Black is exploring the possibility of asking voters to remove the whole-county provision from the state constitution.
The whole-county provision states that legislative districts cannot split counties.
"At this point no one is trying to amend the constitution," Lineberry said. "It's just one of many possible options being considered if the state loses the redistricting lawsuit."
Members of the Republican party filed a lawsuit last November challenging the House and Senate redistricting plans, claiming Democrats violated the state constitution by splitting counties and packing voting districts.
Lineberry said Black has not actively discussed the possibility of an amendment yet because he is confident the state will win the redistricting lawsuit.
Amending the state constitution requires a three-fifths majority vote in both the House and Senate, as well as approval by popular vote.
Although the Democratic party holds 70 percent of the seats in the Senate, it would need to sway 10 Republicans in the House in order to win a three-fifths majority.
Senate Minority Leader Patrick Ballantine, R-New Hanover, one of the plaintiffs in the lawsuit, said there is no way Democrat leaders will be able to sway enough Republican support to pass the amendment.
"I think they would be ostracized for putting themselves above principle," he said. "I don't think people would appreciate politicians that put themselves above what's right for the state."
