 No one wins without the support of delegates, and that's why the Harris camp is trying to reach out to as many people as possible, get as many endorsements lined up as possible. The convention begins four weeks from today, but Democrats are actually pushing to get this done through a virtual roll call the first week of August to lock this away and prevent the chaos and unpredictability of what would be a truly open convention where 4,700 delegates are free to do as they wish. That's exactly what they don't want, and that's why the momentum for Harris.
