"No, the DNC didn’t ‘rig’ the Democratic primary for Hillary Clinton."
It is "not unheard of, for a national committee to align with a candidate before he or she wins the nomination. One example was the 1992 Republican primary, when incumbent President George H.W. Bush faced a primary challenge from Pat Buchanan and the RNC openly stated that “the chairman is 100 percent behind George Bush and so is the committee.”"
"Brazile states that as Al Gore’s campaign manager, she did not start “inserting” staff into the DNC until June 2000. While this is technically true, it misrepresents the level of control Gore already had over the DNC before the 2000 primaries began: By 1999, the DNC’s senior staff was dominated by Democratic politicos with long-standing relations to Gore — including both co-chairmen, the finance chair and one of the senior advisers. Thus, while the DNC did not endorse Gore, it clearly preferred him in the 2000 primaries."

Wait: There is more.
"I had tried to search out any other evidence of internal corruption that
would show that the DNC was rigging the system to throw the primary to
Hillary, but I could not find any in party affairs or among the staff. I
had gone department by department, investigating individual conduct for
evidence of skewed decisions, and I was happy to see that I had found
none."

“I found no instances that the party rigged the process, and I wanted to make sure Bernie and his supporters understood that."
