Via Manuel Álvarez-Rivera:
Voters in Puerto Rico go to the polls next Sunday, August 19, 2012, to cast ballots in a constitutional amendments referendum, concerning the Legislative Assembly’s number of members and the right to bail.
The constitutional amendment on the Legislative Assembly’s number of members proposes a reduction of the number of senators from 27 to 17, and the number of representatives from 51 to 39, starting in 2016. The number of Senate districts would be increased from eight to eleven, but each Senate district would elect one senator, instead of two. In addition, each Senate district would include three House of Representatives districts (instead of five), for a total of 33 House districts; each House district would continue to elect one representative. Moreover, the number of at-large seats in each House would be reduced from eleven to six. Likewise, the minority party representation cap would be reduced from nine to six seats in the Senate, and from 17 to 13 seats in the House of Representatives.
If we go by the cube-root rule, which suggests assembly size tends to be near the cube root of the population, the current first-chamber size of 51 is already only about one third of expected. If this referendum passes, Puerto Rico will have an extremely undersized assembly.
There is some tendency for islands (especially in the Caribbean) to have undersized assemblies. And the cube root rule might not apply to assemblies of not fully sovereign entities (though its underlying theory makes no such explicit claims). In any case, this would be a really small legislature for a “Commonwealth” of around 3.7 million.
