Polling is not a perfect science. Every pollster is going to get an outlier every once in a while. Since one of these things is not like the other with the Rassy poll vs. the rest of the polls out there, it has to be looked at that way.
Just like the Washington Post/ABC News poll does on the Hillary! side. The good news is that we have plenty of data points to look at where we can quickly figure out where the outliers are.
