In any case, 42/26 means that Sanders is near 70% name recognition among Dems. There's only so much more room for him to grow just from expanding name recognition, as opposed to winning over current Clinton supporters who already know who he is.
The funny thing is, if you compare Sanders to must of the Republicans, he usually has better fav/unfav within Dems than may of the Pubs do. But for the GOP candidates, it is just somehow taken for granted that they will be unpopular. Double standard. If they are legitimate candidates, then he clearly is as well.
