This is what I've been saying. The Maine Dems aren't just a rubber stamp that does the DSCC or DNCs bidding. This is where Jerry Brown and Dennis Kucinich beat expectations and the party was able to extract concessions from the DNC for the National Convention. This was always going to be decided by the voters at caucus, not Chuck Schumer, Kristen Gillibrand and the DSCC.
I don't think the MDP realized the candidates would draw up slates of their supporters though. They envisioned 500 unpledged delegates showing up next Saturday, listening to the speeches and then spending the day voting. Instead the room will be full of Jackson supporters, they shouldn't even have speeches and the voting will be done on the first ballot. They should probably cancel the convention and just do it on Zoom. I feel for the people who will drive hundreds of miles to get there just to turn around and go home after a few minutes. They will be fired up to hear Troy but no one is going to want to hear from Bellows, Shah, Costello or anyone else.
