Not a chance Sanders leads by 19 among Hispanics, especially when neighboring Arizona and its Hispanic voters went heavily for Clinton. Throw it in the trash, at least on the Dem side.
GOP voters might be fed up with Cruz trying to game things behind closed doors so there is a backlash against him
623 likely Democratic voters, so I imagine the MoE on the Hispanic subsample is pretty big.
Even if it's not, I always caution about "throwing out" results like this -- we should be selective about throwing out outliers.
