The strategy “redefining” is wrong when the Latinx community is growing faster than any other demographic. You will not win the Cuban-Americans calling what Sanders is doing is socialism. You will not win most Americans with Venezuelan, Colombian, Chilean heritage. I see my parents and my family and friends watching videos of terrible things happening Venezuela and more and more they want Trump and the US to interfere. And these are people who hate Trump. But suddenly intervention sounds like a good idea and it always does when it about you.
Sanders needs to stop thinking of only the white middle class and realize that his PR strategy cannot only catering to them.
