Discontent high prior to Sunday elections

Voter discontent in Mexico is high, and a debate rages over how best to send the political class a message of disgust in Sunday’s midterm elections.

Some academics, artists and protesters urge the nation’s 83.5 million voters to nullify or deface their ballots, even holding up signs along Mexico City’s main boulevard this week calling for such action.

Whatever path they choose, voters — many of them in a foul mood — will elect the 500-seat lower house of Congress, select nine out of the 32 state governorships, and elect legislators and mayors in 16 states.
