Mexico political killings mar election

Mexico is headed for its biggest and possibly most violent election ever.

The biggest election in Mexico’s history is scheduled in less than two weeks; over 3,400 political posts are up for grabs.

These elections are also standing out for the brutality of the campaign season.

There have been 114 political killings across the country, many at the municipal or state level.
