Sullivan Jr. — and that supporters of his longshot rival might not rank the incumbent at all in the state’s unusual election system where voters can pick backup options that get counted if no candidate clears 50% of the initial vote. Two recent polls that simulated ranked-choice tabulations showed Peltola as the victor.”
