If the same be agreed to by a majority of all members elected to each house, such proposed amendment shall be entered on the journals with the yeas and nays, and published in at least one newspaper in each county, where a newspaper is published, for six months immediately preceding the next general election for Senators and Representatives, at which time the same shall be submitted to the electors of the State for approval or rejection. If a majority of the electors voting at such election adopt the amendment the same shall become a part of this Constitution. Only one amendment to the Constitution may be referred pursuant to this section.
