Bullshit.I wonder if democrat voters will ever figure out that their primary votes are meaningless because Hillary is the chosen nominee and what they want simply doesn't matter to the democrat powers that be.
Democratic voters (as well as independents in open-primary states) are as surprised at Sanders' momentum as he is. While he's not likely to win the nomination, he has succeeded in pulling Hillary out of the center and made her rethink (or at least reposition herself) on certain issues.
Some of us would define that as a success.
And that was even before the DNC uproar.
She had to distingusih herself from Obama as well as from Jim Webb so she moved Left. That's where the Dems are these days anyway. The party of Stalin and Pol Pot.
