Slade Mead is a former Arizona State Senator and is Republican turned Democrat.
His eldest daughter, Lindsay, is a special needs child with a rare form of epilepsy, a severe seizure disorder.
Mead managed to defeat Daniels in the Republican primary, and took her senate seat for District 20.
Mead eventually sided with the Democrats, citing a lack of funding for public education.
This event resulted in Mead's exile from the party, and in 2004 State Representative John Huppenthal challenged him in the primary.
