They, courts, don't have to invent anything. "Positions of Public Trust" includes POTUS. You are arguing that the President in not in a position of public trust.
Must the E.O. explicitly state 'elected officials' in order for it to pertain to POTUS?
Your, apparently, saying yes.
"Public trust postions, as cited in the EO, ". . . involve policy making [Doesn't POTUS involve policy making?], major program responsibility, public safety[Isn't POTUS commander in chief?] and health, law enforcement duties, fiduciary responsibilities or other duties demanding a significant degree of public trust[Doesn't commander in chief demand a significant degree of public trust?], and positions involving access to or operation or control of financial records, with a significant risk for causing damage or realizing personal gain." 5 CFR Part 731"
What I do know is that I'm no lawyer, but Dr. Taitz is and she (and the plaintiffs) feel like they have 'something' there.
hmmmmm...maybe they do on second thought. Do we have a link to this executive order?
