If you want to cast a ballot in this year's Aug. 26 primary election, you'd better by register by midnight tonight!
Most of the action is on the Republican side this year, with contested primaries in a variety of state offices—governor, secretary of state, attorney general, et al—and Southern Arizona congressional races. So if you want a ballot with a lot of choices, you should either register as a Republican or without a party preference so you can request a GOP ballot.
You can register online at servicearizona.com. Pima County Recorder F. Ann Rodriguez has a list of local spots you can find a registration form here. Rodriguez will also keep her downtown office open until 10 p.m. tonight for last-minute voters to sign up. Details here.
