Republican challenger Martha McSally is now leading Democratic Congressman Ron Barber by just 179 votes in the tight race for Congressional District 2, following Pima County's tabulation of a batch of provisional ballots.
Pima County Elections officials counted 15 early ballots and 4,889 provisional ballots, according to Pima County spokesman Mark B. Evans, who added that roughly 4,000 provisional ballots remained to be counted.
How many of those provisional ballots are in CD2 is unknown, but in today's count, about 3,210 of ballots counted today were from CD2 and Barber picked up 162 votes.
County officials hope to finish the vote count tomorrow.
