The legislative vote required is two-thirds of the members elected to each house in Georgia, Louisiana, South Carolina and Virginia; two-thirds concurrent vote of both branches in Maine; three-fourths of all members of each house in South Dakota; and not specified in Alaska, but bills require majority vote of membership in each house. |
