Race summary
Jackson, who came in third place in the gubernatorial primary, is extremely popular within organized labor, though this is not one of the stronger states for unions. While he does not have Platner’s personal baggage, he also doesn’t have Platner’s candidate skills. This does not mean that Jackson can’t beat Collins in November, but it will be a real upset if he does.Key Dates
