LOL.  Another one where St. Hillary can do no wrong.  So, you deny Donna Brazile's claims in her book?   Most of the super delegates were bought and paid for even before the primaries began so Sanders started at a extreme disadvantage.   Add to that the facts that the DNC only worked for Clinton and you have the beginnings of the rigging.   As far as the crossover, there were not many open primaries.
Also, it is not bile or propaganda if it is the truth.  Do you also deny that Hillary bought the FusionGPS propaganda that is being used against Trump?   Do you deny the Clinton Chinese connections?  If so, I am sorry for you, because you have bought into the propaganda of the people that have been actively destroying the country.
