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'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'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.
