Not sure I can see how democrats threw Hillary under the bus, or Ferraro, for that matter. To use your - ahem - "logic", then I guess republicans threw Giuliani, Romney, and Huckabee under the bus this time, and McCain under the bus last time? Of course, they probably will never throw any woman under the bus, as I have yet to see any woman or minority widely supported for President by that political party. Dare to dream, eh?
What exactly do you mean by "throwing under the bus?" If you mean a majority of delegates decided they preferred Obama as throwing somebody under a bus, I don't know what to tell you. Further supposing if Hillary had won, your ANALogy would have been that the dems threw a black man under the bus.
