God I hate Rasmussen's website. Not for political reasons, not for bias, just because it's so awful.
Well, this can't be it - this says 33% of Likely U.S. Voters of any color think life for young black Americans has gotten better.

Besides, honestly, it's V's responsibility to fish out this magic poll at this point, not yours.
