But we are in this situation largely due to the "blur-the-differences" mindset Bill established in this party.

We lost the electoral college in 2000 largely due to that mindset(we'd have won if Gore had stayed with his "for the people, not the powerful" line, because Nader's vote would have collapsed).

At some point, you can't expect people to keep turning up to the polls if all you do is run a "keep them OUT!" campaign.

Hillary had a great platform, a platform which was improved by the Sanders language that was added. The campaign ads hardly mentioned it. Instead, the focus was almost exclusively on a "stop Trump!" message. This choice convinced a lot of voters that we had no positive proposals to offer. We did have those, but the ads didn't mention them and the stump speech didn't mention them enough.

All of that is the result of Bill's argument that the Right has won the argument on most issues and that Democrats must always campaign by promising nothing but Reaganism-with-a-human-skin-mask, that we can never run FOR, only AGAINST-and not even against that much.
