There's a clearer and clearer pattern that in states where Bernie Sanders' name recognition matches Hillary's (or comes close to it), he does not only have a FAR higher favorable rating than her among all RV, but he also strongly outperforms her among GE matchups against the GOP.
The problem for Bernie is that he only has a 30-40% name recognition right now in states other than IA/NH/SC/NV and therefore trails the GOP there and nationwide.
But in NH and IA, where he's well known and popular - he's actually the best bet for the Dems.
So, Hillary-supporters: Jump on the Bernie-train as fast as you can
