Sanders has a pretty lengthy bunch of DNC platform proposals alone and this doesn't even account the racial justice side of things or Israel-Palestine as he has appointed Cornel West and a Palestian activist to the group writing the platform for the convention. Nor does it go into the changes he wants to make concerning the primary process and including younger/poorer activists into the party's fold rather than letting it be headed by older, whiter and richer individuals.
Taking from this lengthy interview:
Bernie Sanders: He Speaks About Attacks, Democratic Platform
What are the top four or five policy proposals you want to convince the Democratic Party to adopt at the convention?
We start off with the assumption that in some areas, there’s going to be broad agreement already. I don’t think there’s going to be much of a debate, frankly, that we need to raise the minimum wage actually to $15 an hour. We don’t have to waste time on that. I think that will probably pass quite overwhelmingly. Secretary Clinton has not come out for the [New York Sen. Kirsten] Gillibrand bill which is in the Senate on paid family and medical leave. I don’t think there’ll be much debate on that. I think we’ll have that as well.
I think the issues of contention will be the understanding that Secretary Clinton has been wrong in supporting virtually every single one of these trade policies. I think what this campaign has shown is that working people understand that NAFTA and CAFTA and PNTR with China have been disastrous for working families. I think there will be some opposition to my point of view but I have the feeling that we’ll win that debate as well.
Secretary Clinton has come up, as usual, with a very complicated and convoluted approach on higher education. You got to spend half your life filling out forms and checking your income every day. I’m not sure that we will not win fairly easily on the issue of making public colleges and public universities part of what we consider to be public education, making it free. I suspect we’ll win that one as well.
I think the real debate will center around how aggressively we take on the fossil fuel industry. I will push for a tax on carbon. Secretary Clinton now opposes that. I think the crisis on clean water is one of the evolving crises in our country around the world. I think you’ve got to ban fracking.
I think a very contentious issue of where there will be a debate—serious debate—and I think we have a shot to win. When I tell you we’re going to have a debate, almost all of my supporters will be supportive and then we can get some of Clinton’s supporters. I don’t think it’s going to be, these votes will come down all Sanders versus all Clinton. And I think, you’ll see, you’ve got progressive people, you’ve got Clinton with the support of some unions there, and some of those people will come over to us on the issues.
I think a contentious issue which we have a shot to win is whether or not we break up the large financial institutions and we create a new financial system not based on a handful of giant Wall Street banks. That will be contentious. If I were a betting guy, I’d think we’d win that. But we may not.
I think the polls suggest that among Democrats there is strong support for a Medicare-for-all, single-payer system. And my guess is we’ll probably win that one too. We may not. But I think we’ll win that one as well.
The other issue that will be contentious is tax reform and making sure the wealthy and profitable corporations start paying their fair share of taxes.
So those are a few of the issues. I think we’ll win most of them. I think the Wall Street fight will be a difficult one, it may not be, depending on the wording of tax reform, that will be tough. Medicare-for-all I suspect we’ll win but we may not.
