The vote for the two empty seats was combined into one vote, instead of each seat being voted on separately. This disadvantaged one of the candidates, Kalyn Free, a Native American women. As I note above, DNC rules require that the national party's executive committee "shall be as equally divided as practicable" along gender lines. As DNC members met earlier this year for the multi-hour process of voting in a new slate of officers, the vote for the three vice chairs being the last position to be filled, it became clear that the party needed to elect at least one man to the final two vice chair spots to maintain the required gender equity on the seven-person executive committee.
The party then decided to hold a single vote to decide the final two slots instead of holding separate votes for each position.
Free claimed that the combined ballot unfairly benefited Hogg and Kenyatta, the only two men left in the race, because members had to vote for at least one man on the combined ballot. She argued it's possible they could have voted differently if the ballots were separated.https://www.democraticunderground.com/?com=view_post&forum=1014&pid=3458178
And this isn't about David Hogg. As Malcolm Kenyatta stated:
I worked my a-- off to get this role and have done the job every day since I’ve held it,” he said in a long thread on X. “This story is complex and I’m frustrated—but it’s not about [David Hogg]. Even though he clearly wants it to be.”
