Also, Sanders's state thus far is overwhelmingly white, and with the snafus like at Netroots this past week, I don't know how well versed he is to speak on issues of race while Hillary has been speaking about women's issues and issues of race publicly for a long time during her career as first lady and a politician. It's sort of while that issue at Netroots is an interesting microcosm to the Sanders campaign and the tricky issues that Sanders has going forward dealing with race. Talking with economic rhetoric is not enough.
In fact, I don't think any Democratic candidate at the moment are truly engaging with African-American constituents and the justifiable anger that exists over issues of police brutality and criminal justice reform. Hillary's probably given the most policy-specific speech on criminal justice reform, which goes back to her history at engaging with people of color. Obviously,
this has not always been the case, but she's spoken extensively about it on the campaign trail and comes across as extremely earnest and compassionate about the issue. That, coupled with her husband's history with minorities and people of color, it shouldn't be that much of a surprise she's polling better with these constituents than Bernie.
