In addition to not wanting to preach to the choir, I think there is legitimately a swathe of FoxNews watchers who maybe felt let down by Trump and some other conservatives failing to fulfil their populist promises and continuation of giving more breaks to the rich than the working class. Bernie can probably reach these viewers with his pro worker messaging, whereas most mainstream dems can't. Hopefully this translates to moving these voters to vote for candidates speaking to these same points, especially in primary campaigns.

People complain that "both parties are the same". This is mostly overstated, but it is very true when it comes to neo-liberalism and pro-captial. I think Bernie is trying to reach out to the swing voters who are sick of that.

this is about to veer offtopic but do you think FOX would actually publish the same article written by a more mainstream Democrat like HRC ? probably not
