Everyone agrees there's a homeless crisis in the US. Plans to address it vary among mayor candidates

Homelessness is at the top of the agenda for candidates in mayoral races across the U.S. West. But they differ on whether it's OK to clear encampments that have spread as the crisis has deepened and how much to rely on temporary housing. In San Francisco, Mayor London Breed is facing serious challenges from four other Democrats in the November election. While they don't agree on how to fix the city's problem, they do agree Breed isn't effective, even as she launches a new round of crackdowns on encampments.
