Until the 2000 election, PRI presidential candidates were chosen by the incumbent president, under a system called "tapadismo." But for the first time ever on Nov. 7, voters had the opportunity to select their party's nominee in a primary election. The party's slogans stated: "Tú eliges al candidato" or "You choose the candidate."
The PRI has been criticized in the past for its internal selection of presidential candidates. A term called "el dedazo" -- or "the big finger" -- has also been used to describe the system. The "big finger" refers to the pointing finger of the incumbent president, who is signaling his heir to the office.
In the first primary contest, there are four candidates whose professional backgrounds extend from law to economics. Each has been a long-time member of the PRI -- and at least one has been under consideration for the "dedazo" in the past. Francisco Labastida Ochoa was chosen as the 2000 nominee.
