Fans and followers of Bernie Sanders keep complaining that it is the "establishment" that is pushing Biden´s campaign.
But if we take a closer look and ask: who were the main voters for Biden on "Super Tuesday"?
Afro-Americans; women; people living in Suburbia.
Well, if this is the "establishment", Bernie should try to reach out to them and win them over because without them, he'll never win the nomination, let alone become POTUS.
The establishment is who is selling Biden, and the voters you mentioned are buying, but Bernie has always reached out to them. The buyers and sellers are not the same people. The sellers are marketing to the fears of the buyers.
Sometimes fear can’t be reasoned with, but it can always be exploited. Bernie’s just not an exploiter.
