MEXICO CITY — Mexico’s presidential election, which has brought the party that governed the country for more than 70 years to the point of ruin, was the latest in a string of blistering defeats for incumbent parties across Latin America.

Recent elections in the region have delivered decisive losses to governing parties of all political stripes.

But while corruption, violence and inequality have been major issues in each country, no single ideology or issue explains the rejection of establishment politics. Voters, analysts said, are simply looking for new options, or at least different ones.

Some countries, like Mexico, have tacked left; others, like Colombia and Chile, right. Often the move is in the opposite direction of the governing party, but not always, as was the case in Costa Rica and Ecuador.
