Populist Reform of the Democratic Party

As far as I can tell, HRC has not taken any policy positions this year.

Statements such as (paraphrased) "I will be a fighter for the middle class" or identifications of problems within the areas of income inequality or climate change are NOT policy positions. They are just statements which are similar to the statements in the OP.

She says she will be a fighter. He says she has not been based on his experience, her past, and what he believes we need for the future. He expresses some other opinions about voters that are opinions and can not be wrong.

As far as HRC's past policy positions. Many of them were wrong and moved us on the wrong direction in the opinion of anyone who would agree with the OP. Again just a guess, but you would not want to address her past "policy positions" and many of her votes on war and peace issues, foreign policy, free trade, fracking, wall street, bankruptcy etc. Even her most progressive task in the Clinton White House (his attempt for health insurance reform) was private insurance based and not based on medicare. Those past votes and policy positions have been posted and discussed numerous times. Demanding them here was just disengenous. Address them where they have been discussed and explain why her votes and policies now will be different than what she has done in the past.

Ultimately, my belief is you will fall back on the argument of every other HRC supporter that I have seen: She is better than a republican.

HRC has good history on statements and votes on issues of women's equality which is a good (great ) thing but is not the only thing. All democrats would or should share those "policy positions" and goals but have better policies and goals for every other issue that should be of concern to democrats.
