This is a 7-Day Tracking Poll which will end Monday Night I believe.
Personally in general I think people have written off McSally too soon. While I don't think she'll win by 7 I still think she has a chance to win.
We'll know pretty early on Tuesday when AZ Polls close and the vote is tabulated if Sinema had any kind of Early Vote lead as most of the Polls are suggesting contracting the Raw Ballot Advantage Republicans seem to enjoy in the State.
I believe McSally is up 5. Republicans have to stay home for Democrats to win Arizona, and we're not seeing that in the early voting.
