In Mexico’s political system the mechanism of the popular vote has a place, but that place is typically reserved for junior persons who merely aspire to a political career. The senators and federal deputies who will become the leaders of the key committees will be those who take their seats by a uniquely Mexican system known by an untranslatable name of “plurinominal.”
The idea, as described in MEI Report 566 (“Introduction to the Mexican Congress”), is that 200 of the 500 seats in the federal congress are reserved for persons who will be named by party leaders on the strength of the showing of the party in the popular vote in each of 5 electoral regions (called by another untranslatable name of “circunscripciones”).
Of those who will likely occupy leadership positions few will have taken their seats by popular election; most will be appointed by party leadership on the basis of kinship ties, union power or former government service. On the PRI list, for example, there is a niece and a nephew of a former president of Mexico.
