Reason to be skeptical of calls for Dems to appeal to white-working class again. GOP doubled-down on their white base with Trump and won instead of appealing to more diverse voters.
The election came down to less than 1% margins in three rust belt states. You honestly don't think democrats could've swayed just a few more of this demographic to pull out a victory in 2016?
Hillary Clinton never even stepped foot in Wisconsin during the general election. Democrats took these states and these voters for granted.
I can understand democrats trying to increase minority turnout for 2020; this makes sense. But trying to win over moderate upper class suburbanites to replace the WWC voters that are bleeding from their Party? Forget about it.
There is room to grow among the voters that swung to Clinton; more upper-class suburban whites to win in the Midwest. Kent, Waukesha, Ozaukee for example. Also Chester and Bucks in PA.
Though I see your point. Dems need to find an opening somewhere.
