President Trump is working to enthuse his supporters with rallies full of grievance and conspiracy, harkening back to his successful 2016 run.

Sam talks to Lisa García Bedolla, a scholar of Latino politics, about how the word "Latino" encompasses diverse communities of all political stripes and life experiences, and he checks in with the former mayor of a small town in Texas who's been thinking of Latino voter outreach for a long time.
