From the New York Times, September 5, 1964:
CITIZEN ISSUE RAISED IN GOLDWATER SUITFrom the New York Times, October 3, 1964:SAN FRANCISCO, Sept. 4 -- Senator Barry Goldwater is ineligible to become President because he was born in Arizona when it was a territory, the California Supreme Court was told today.
Suit to Remove Goldwater From Jersey Ballot Is LostJudge George H. Barlow ruled that Senator Goldwater, the Republican Presidential candidate, is a natural-born citizen, even though he was born in Arizona ...
I suppose that those court rulings in favor of Goldwater can be useful as precedents for McCain, should his status as "natural-born" be challenged in court this year.
