What evidence do you have to suggest the momentum has shifted back towards Hillary?

By ‘diversity’ you really mean ‘black.’ The latest polls show the candidates neck and neck in Latino support. Hawai’i is among the least white states in the Union, and it went overwhelmingly for Sanders.

In every contest, Sanders increases his share of the minority vote. And in the states that remain, only 15% of voters will be black. Not insignificant, but not overwhelming either, especially given that black voters from non-Confederate states have, over time, been increasingly drifting towards the Sanders campaign.

So I’m not sure you can rely on those arguments. When Hillary shows some electoral resilience, I’ll buy it, but in the meantime, you’re clutching at straws.
