First, JC Fremont wasn’t elected.
What does that matter? He ran for president on the Republican ticket. That means the Republicans supported him and had no issue with his citizenship.
Second, if memory serves me correctly, Chester Arthur burned his records shortly before his death, “cleverly” concealing a lot of things from posterity.
What does that matter? The fact his father was a British subject was publicly known when he ran for Vice-President, which has the same requirements as President. Oh, perhaps he burned secret instructions from Queen Vicky on how to overthrow the American Republic and restore the country to rightful British rule?
“The fact his father was a British subject was publicly known when he ran for Vice-President..”
Not so, his father became a naturalized citizen 7 years after little Chester’s birth......Chester made a conscience effort to hide this fact and evade the Article II eligibility question ‘til his death.....
