Rational people wouldn't see it as a slur. However, if this sentence had come out of the mouth of a Republican, much like "Plugs" Biden's "clean" remark about Osama Obama, it would be front page news (above the fold)......for weeks.....
Yes, it is a stretch, but you are all coming to the same conclusion that a Republican would be near run out of town for the weekend if he said the same thing.
That’s the point.
