Election of Delfina Gómez as governor of Mexico state signals decline of PRI

The PRI – once the overwhelmingly dominant party of Mexico in the 20th century – is now a weak and also-ran political force

Mexico’s oldest party has lost control of the country’s most populous and influential state, in an election result that could signal the end of a powerful network that has dominated politics in the region for almost a century.

Alejandra del Moral Vela – the candidate for the incumbent Institutional Revolutionary Party (PRI) which has governed the state of Mexico uninterrupted since 1929 – was beaten by eight points on Sunday, despite claiming victory during the vote count.
