The chief of staff to a POTUS or VPOTUS need to work well with the elected official they serve. The position requires a lot of trust on both ends. It stands to reason then that Liz Allen has probably already worked with the VP nominee. I checked, and Liz Allen and Pete Buttigieg have worked together, specifically to prep Harris for the 2020 VP Debate. Does that mean that Buttigieg is the nominee? https://www.nytimes.com/2024/08/02/us/politics/elizabeth-allen-kamala-harris-campaign.html
