Interesting that the article talks about how broadly popular Warren’s ideas are as a way to appeal to moderates, but somehow Bernie’s apparently aren’t?
It's a framing issue more than anything else. Warren frames her proposals around sound policy that benefits the working people, while Bernie has carried the "Democratic Socialism" label alongside his proposals.
Upon closer inspection, both of their policies are similar and reach the same goal. To the naked eye, so to speak, Warren's position is perceived as more palatable simply because of how she frames the conversation.
Perceptions are crucial.
Thats true. But at the same time, when Bernie proposes the same policy as Warren, the instant reaction is 'unrealistic radical proposal that will never pass' while Warren gets the reaction 'she has solid ideas'. The media perception right now is that Warren is an idea candidate while Bernie is an ineffective gadfly.
Warren successfully changed her image from silly stuff like Pocahontas to the policy geek by floating lots of policies. Now its Bernie's turn to change his image, and I think he should do it by somehow getting across how effective he has been in Congress. I dont know if he can...
