This is the politically correct answer, it's not wrong to admit that large portions of the voter base are wary to vote for candidates, not because of a legitimate disagreement for their policies, but out of ignorance, complacency, superficial wariness, and misconceptions about their opponents.
Which isn't the say the reverse isn't the case because I know black people who aren't voting for Bernie because they have policy disagreements, but to act like the reverse of that isn't a factor just because you don't want to make claims about a minority voter base is just ridiculous, especially if you're willing to do it for white voters which I know people on here are willing to do.
Bernie speaks out against private prisons while his opponent takes money from them, he wants to remove Marijuana from being schedule 1 drugs, he wants to make it so people dying in police custody automatically triggers a federal investigation, he wants to get rid of voting laws that specifically target minorities, and he wants to implement economic policies that inherently benefit all American's regardless of race, and if black people aren't voting for Bernie because he focuses on economics than they probably shouldn't be voting at all, especially if they think Clinton is any better on it, or maybe that's my bias as a black Bernie voter/occasional volunteer speaking.
What brilliant idea do you have in regards to fixing racial inequality that Bernie should be proposing?
