Age: 67
Occupation: Arizona Governor
Under the leadership of Republican Brewer, Arizona has faced off with the federal government like no other state in recent memory. Amid accusations that the Obama Administration failed to protect Arizona from illegal immigration, Brewer championed a strict legislative crackdown that the Administration will challenge this year in the Supreme Court. Brewer has criticized President Obama for blocking uranium mining near the Grand Canyon and was photographed having an intense exchange with Obama on the tarmac at Phoenix's airport in January.
