PHOENIX — Arizona Republicans are trying to remain positive as Democrats cut into their once-massive advantage in early voting as they hope GOP Rep. Martha McSally can beat Democratic Rep. Kyrsten Sinema to take an open Senate seat only days before the November election.

After Republicans held nearly a 12-point advantage following the first two weeks of early voting, that edge has been trimmed to less than 8 points (41.8-33.9), along with nearly 24 percent unaffiliated voters comprising the rest of the vote, making some Republicans nervous ahead of Tuesday. The early vote is expected to comprise of roughly two-thirds of the entire electorate.
