The blogs are filled with Sanders supporters who are stating flatly that they will not vote for Clinton, regardless of her opponent. They see her as Republican-lite and are debating whether to skip the presidential line on the ballot, skip the election entirely, fill in Bernie's name as a write-in (which will not be counted in most states), or look for an alternative. The alternative mentioned most frequently is Dr. Jill Stein, the Green Party candidate for President, whose views often parallel Bernie Sanders'.
Conversely, I have not heard any suggestion anywhere that Clinton Democrats would refuse to vote for Bernie Sanders in the General Election.
My conclusion? If the Democratic Party wants to win the White House in November, Bernie Sanders on the ballot is the way to make that happen.
