A caravan of migrants now crossing Mexico

The caravan of Central American migrants traveling through southern Mexico on Wednesday - estimated at around 7,000 people, nearly all Hondurans - has attracted headlines in the United States less than two weeks before the midterm elections. But most of those walking through blistering tropical temperatures, sleeping on the ground in town squares and relying on donated food from local residents, are unaware of US political concerns or even that there's a vote coming up. While they commonly cite the same core reasons for migrating - poverty, violence - their individual stories are deeply personal. Reuniting with family in the US is something those on the road north frequently speak of.
