I think the fact that the Dems ran Clinton despite more support in key demos for Bernie shows that as of right now they aren't very interested in following data if it conflicts with their other agendas.
If this trend continues and extends down to congressional elections, etc. for both parties as it is now (Republicans ready to follow data to build campaigns, Democrats playing out of an opaque narrative), this could spell bad news for the future of the American Democratic party.
It's funny because people were playing this exact card during the 2012 election due to Obama's tech-savvy reëlection effort. A lot can change in four years.
