Clinton supporters would like to blame Sanders; it's a shame, they think it's ok to be really nasty to Sanders supporters and then expect them crawling back begging for forgiveness for not following their Borg collective, in the first place. Everyone is free to vote their conscience, but no because most Sanders supporters will likely vote for Clinton. No sane person wants Trump to be POTUS for obvious reasons.
Some Sanders supporters won't vote for Clinton because they wouldn't have in the first place.
That is neither the fault of most Sanders supporters, and certainly not the fault of Sanders himself, who cares about the future of this country and is doing his best to get elected POTUS which has been his only objective all along; it's a shame Clinton supporters can't see that.
Clinton should be thanking Sanders and his supporters, they have given her the opportunity she otherwise would not have had, to get her message out there.
Completely ignores the fact that anyone who doesn't support Sanders is labeled a "Hillary shill" and any news that's true that doesn't support their view is "part of the main stream media that's holding us down and lying" and that "Hillary can't win any states without fraud". Oh and don't forget "why are black people so stupid and not voting for Sanders?".
