Just got a report from a friend who lives in south Chandler (fairly affluent, overwhelmingly GOP suburb of Arizona). Said that the lines were like nothing he'd ever seen before. I'd like to think that's good news, but heavy turnout is something that normally works against us.
Republicans never used to do get-out-the-vote things (the Dems always did!), but this year they are. (I think I read the Rs first tried it in the last congressional elections for practice and were pleased with the results.)
