Sanders: The Dems have abandoned the working class

His interview on Meet the Press. He criticized the Party for not going after corporate corruption enough or helping the working class enough. Yet, he praised Biden for his economic policies that indeed helped the working class and the economy. And then there is  Harris' commitment to doing more of that, as well as punishing corporations for price gouging. But Trump won with policies that will obviously further raise prices and hurt the economy. 

So is it really who has the better messaging? And is hate and bigotry really better than love and inclusion?
