the amendment seems to have a typo, as it reduces the number of at-large senators to six in article iii section 2 but not in section 1, where it still says nine:
Modify Article III, Section 1 of the Constitution as follows:
(...)
3. The Senate shall consist of eighteentwelve Senators; nine elected at large and one elected for each region and each subregion. However, this section shall not be construed to prevent any duly elected senator from completing any term to which they have been elected, with the full rights, powers, and privileges of said office.
(...)
Modify Article III, Section 2 of the Constitution as follows:
1. The manner of election for at-large Senators shall be as follows:
i. The nine six at-large Senators shall be elected for a term of two months by the eligible voters of the Republic according to a method of proportional representation prescribed by the Senate. Elections for the seats shall be held in the months of February, April, June, August, October, and December.

therefore i think i have to vote
