Institutions suffer when power is concentrated for too long.
Stagnation settles in. The reluctance to loosen one's grip on the machinery of power invariably breeds corruption. Such was the case with the PRI, which earned a reputation for ruthlessness, graft and for cozying up to Mexico's drug kingpins. Mr. Fox, a former executive with Coca-Cola in Mexico, deserves plaudits for heroically standing up to the establishment and its entrenched interests. Mexico's voters should be applauded for recognizing a change was needed and for taking advantage of the choice presented them.
