With all but two votes counted in Cochise County, Republican challenger Martha McSally now leads Congressman Ron Barber by 509 votes.

Here in Pima County, an estimated 3,000 ballots are ready to be counted by the Elections Department this weekend, along with an estimated 9,000 provisional ballots that may or may not turn out to be valid. It's unclear as to how many of those are in Congressional District 2.

Both Barber and McSally are soliciting contributions to help pay for lawyers and other expenses in the event of a recount.

More numbers to come as we get them. County spokesman Mark B. Evans tells The Range that Pima County will not post new results before Monday.
