Someone tried to use this claim against George Romney back in 1968. Not USA born.
Some shyster lawyer tried the same crap against Goldwater (born in Arizona before it was a state) in ‘64.
This never became a problem because they never became the presidential candidates of their party. They dropped out before that.
The NYT should have waited for McNutty to become the candidate of his party before springing this.
Goldwater wasn’t a Presidential candidate?
