We have to reckon with the fact that Uncommitted really was what it said it was - a group of loyal partisan democrats trying to save the party from itself. This was obviously not the case with "Abandon Harris," but anyone conflating the two is doing so out of either ignorance or malice.
The co-founder of the 2024 National Uncommitted Movement, Abbas Alawieh, decisively won his primary to become a State Senator in Michigan. Abbas was endorsed by both Bernie Sanders and Gretchen Whitmer. Abbas Alawieh also privately met with former VP Kamala Harris last month upon her request.
