The truth is the only way the democrats can win the general election is with either Hillary or Biden.
Bernie has some great ideas but he is too leftist and alienates himself from moderates. There is no way with his ideology that he would win. Part of the reason Hilary is so shifty is that she knows she must appease democrats to win the nomination. Bernie is killing her on this. But she always has to consider what the general population wants to hear. If she is too leftist they will abandon her, if she is not enough the Democrats will which will lose her the nomination. If Bernie gets it the democrats will lose the general election.
Regardless the only way democrats can take back the white house is with her even with all the scandals. Sanders is great but he will never win and gain support with undecided voters.
