Brewer gigged on voting machine policies
Blogger Brad Friedman (bradblog.com), who follows voting machine issues, sees Jan Brewer as "one of the country's absolute worst secretaries of state" and trouble for the state when she becomes Governor:

Brewer signed the contract ... to bring unverifiable Diebold touch-screen voting systems into the state, long after they had been shown by computer scientists and security experts to be inaccurate, unreliable, and easily tampered with. She has been aggressively opposed to virtually every move towards transparency and citizen oversight in her state's elections, in favor of purges and restrictions against legal voters at the polls, and even went as far as to publicly call her own citizens who spoke up against her embrace of the use of unverifiable Diebold voting machines "anarchists" and "conspiracy theorists."

She and her office have also blatantly lied to their citizens about their voting machines, and subsequently were so cowardly that they even refused to discuss the issue on air with us, in a setting friendly to them (because they know we would have called them on those lies).
