I checked the results; the opposition totaled up still would not have amounted to a McCain loss.
With more of the results in now, Pima County’s vote went:
MCCAIN, JOHN 36,423 - 49.96%
WARD, KELLI 30,495
MELUSKEY, ALEX 3,540 - dropped out of the race but name still on the ballot
VAN STEENWYK, CLAIR 2,446
Total Votes 72904
Pima County tends to vote liberal. Home of Tucson and the U of A.
