US Representative Alexandria Ocasio-Cortez will reach the constitutionally required age to be eligible for presidency mere weeks before the 2024 Presidential elections. This means she definitely is eligible on the inauguration day in late January, and on election day itself, but she would be slightly younger than required during most of the early voting and mail-in ballot voting period, and she would definitely be under the legal requirement during the primaries and the official nomination event of her party.
So the question is: at what point must a presidential hopeful meet the constitutional requirements for eligibility for President?
