Amendments to this constitution may be proposed by any member of the senate or house of representatives. An amendment so proposed, approved upon roll call by a yea vote of at least a majority, but by less than three-fourths, of the total membership of each house, shall be published with the laws which may have been passed at the same session and be continued to the regular session of the general assembly elected at the general election to be held on the Tuesday after the first Monday of November in the next even-numbered year. An amendment so proposed, approved upon roll call by a yea vote of at least three-fourths of the total membership of each house, or any amendment which, having been continued from the previous general assembly, is again approved upon roll call by a yea vote of at least a majority of the total membership of each house, shall, by the secretary of the state, be transmitted to the town clerk in each town in the state, whose duty it shall be to present the same to the electors thereof for their consideration at the general election to be held on the Tuesday after the first Monday of November in the next even-numbered year. If it shall appear, in a manner to be provided by law, that a majority of the electors present and voting on such amendment at such election shall have approved such amendment, the same shall be valid, to all intents and purposes, as a part of this constitution. Electors voting by absentee ballot under the provisions of the statutes shall be considered to be present and voting.
