Via NBC News: Clinton Lead Over Sanders Among Latino Voters Rapidly Narrowing
among Hispanic voters, what had been a two-to-one or better Clinton lead for the past six months has narrowed dramatically in the two weeks following the Iowa Caucuses. Where our surveys had shown Clinton leading by 20 percentages points or better during December and January, her advantage had reduced to just three percentage points (46 to 43 percent) on our most recent week of tracking (from February 8-February 14).
The Clinton firewall among African American Democrats, on the other hand, remains intact. In the past week, she led Sanders among black Democrats nationwide by a whopping 52 percentage points (70 to 18 percent), roughly comparable to the margins Clinton has enjoyed so far in 2016.
