D. The fourth big takeaway of the fall of the @BernieSanders campaign is that in order to win the Democratic nomination, you. have. to. win. black. voters.

You can& #39;t fake this point with token hires, celebrities, and pandering. You have to actually listen to black voters.

E. My last big takeaway from the @BernieSanders campaign 2.0 is that you can& #39;t win the Democratic Party nomination without trying to build the largest majority possible - more than 51%.

Democratic politics is about addition and multiplication - not division and subtraction.
