While the report states that one person needs to be in charge, it also noted that grassroots groups are going to be active in any campaign and that it's more effective to "channel" and "focus" those groups, rather than "control" them.

"Right or wrong, there is a feeling that volunteers were too restricted in what they were asked to do and that sentiment will carry forward to the next effort," the report notes.

At the same time, campaigns are by their nature focused.

"We understand how hard this may be to hear for a large, diverse, egalitarian movement," the report states. "... But the hard truth is, that while a movement such as this can be run as a democracy over the long term, once you're actually in a campaign, things are different."

To make everything work, one person has to be in charge and that person, "cannot be overly concerned about whether or not he or she will be 'liked' after the election," the report states.
