Maine Democrats have formally nominated Troy Jackson as their candidate for the state's critical Senate race. The selection was made during an unusual party convention.
Jackson will replace Graham Platner, whose previous nomination was described by some reports as a "debacle." This particular Senate contest is widely considered a must-win for Democrats.
Jackson has now officially clinched the Democratic nod to challenge Collins for the Maine Senate seat. This is a developing story and will be updated as details emerge.
