Randy Kendrick, wife of Arizona Diamondbacks owner Ken Kendrick, is the highest spending donor against an initiative what would legalize recreational marijuana in Arizona.
An ABC15 analysis of state spending data found that Kendrick has contributed $100,000 against Proposition 205.
Kendrick and other anti-pot donors have outspent pro-pot donors almost four to one.
She could not be reached for comment Friday, but the top pro-pot donor, Tempe attorney Steven White, who has contributed $55,000, tells ABC15 that he was not always for marijuana.
But, several legal cases, such as 7-year-old Zander Welton, changed his mind. In the Welton case, a federal judge had to rule in favor of him receiving marijuana extract to treat his seizures.
"It was not up until 2011-ish where I saw it having a positive impact in people's lives," White said, noting that he is now a registered Independent.
