Which former president did Ronald Reagan campaign for during the State of California's governor race?

VelourBanjoPlayer141, The only person on the list, that had been a president, was Richard Nixon. I heard someone say once that history would show he was a good president. The country demanded his resignation because he lied. How innocent the American people were.

Daybonn, lied cheated burglary…..

Kind of easy when only one of the choices was ever President.

I guess a lot of people were thrown off by "California governor" in the question, oddly, as it states that particular governor was a US president, which Arnold Schwarzenegger hasn't been and lawfully cannot be.
