It was the best case scenario from the National Action Party's (PAN) hypothetical concertacesión playbook. The sitting Party of the Institutional Revolution (PRI) president congratulates the PAN challenger on the very night of the election, preempting any need to press their postelectoral case through the courts or in the streets. While Vicente Fox's defense of the vote team and the PAN relished their victory and reveled in the fact that they would not have to engage in their usual three-day postelectoral complaint-filing marathons, the PRIístas were not so pleased with Zedillo's announcement. Rumors circulated in the days after the election that Zedillo had betrayed his party for a place in history as Mexico's great democratizer. And while being a gracious loser may have been part of Zedillo's bid to be the hero of courting democracy in Mexico, it was viewed as disloyal by a party that held power for generations precisely by valuing loyalty as the highest trait.

If the PRI bureaucracy's immediate response to Zedillo's recognition of Fox was simmering contempt, it boiled over in the following months in a PRI-on-PRI postelectoral conflict in Mexico State claiming dozens of lives and in protests by outgoing governors in Tabasco and Yucatán against the federal electoral court's unprecedented interventions in state elections.
