The DNC superdelegate argument is tough because Hillary still won the popular vote.
But Obama beat Romney by 5 million. The greater the difference in the popular vote, the less likely we’ll see flukes in the electoral vote. Hillary appealed to the wrong areas. Sanders had more universal appeal and seems like he would have likely garnered more electoral votes.
I actually meant that she won the popular vote against Sanders in the primaries.
The Sanders what if is a tough question. On the one hand it does seem like he was more liked in the places Clinton ultimately lost. But we have no idea what the discourse would have been like. Hard to imagine a self proclaimed socialist having more universal appeal in the US.
