Pima County Democrats generally put up an incredibly strong vote harvesting effort which means that they dominate the early ballot process. Republicans have to win heavily at the polls and that's what happened this time around. Barber won the mail in ballot portion of the race 53/47 but when people actually went to the poll to cast their vote he lost 41/59. My guess is that McSally won because she has a compelling story and Barber was more moderate than what the moonbats down here thought they should support. The Democrats just didn't get the turnout they thought they would.
