You really believe the establishment will care about a few votes or more aptly non votes? They certainly haven’t cared since 2016 since they knew the inner workings of the Hillary deal.
The democratic establishment knows they need votes, and those votes aren’t in the social, democratic, liberal bastions. After all the Democratic's have won the public vote how many times in a row now?
They need the swing/moderate voter states/counties that they lost last presidential cycle. If the candidate doesn’t market to that crowd, any candidate can kiss the General goodbye.
And yes, I agree the electoral college needs to be abolished. The fact is though it’s still in full effect and why most educated voters I know feel trump would still win again(especially with bernie).
As I’ve said getting the senate should be anyone’s(Socialist, Leftist, Liberal, Democrat, Moderate, Etc) priority over the executive branch because if they keep the house and take the senate. Trump can kiss his presidency goodbye and policy will actually get passed in Congress onto the executive branch and poo will come to a head.
