Miles Coleman, associate editor of Sabato’s Crystal Ball at the University of Virginia’s Center for Politics, said that O’Halleran’s district currently leans Democratic, with 36.2% of voters registered as Democrats to 32.4% registered Republicans. But he said “if Yavapai County gets put back in, O’Halleran could have a much more red district” in District 1, which covers most of northern and eastern Arizona.
