I'm not saying that the president will control who will vote but it would certainly be a violation to Article 14 Section 1 if the president controls who can vote and who can't, its all common sense that anyone with an ID can vote, but otherwise good point...
Article 14: The Rights of Citizens
Section 1: The government shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or restricting the freedom of speech of the press or the people; or the right of the people peaceably to assemble, protest, or petition the government for a redress of grievances. Imgflip TOS still applies.
Also, all the president does is that they can issue IDs to users who don't have an ID or are wanting to update their ID
