The statute is unconstitutional if applied to the president. The only qualifications for president are contained within the four corners of the Constitution.
Hillary Clinton isn't the president.
Even if she were, the law is the law. Nixon was nearly impeached for similar transgressions.
This isn't about the basic constitutional requirements for eligibility. Don't confuse that with the issue at hand.
She's guilty of having violated the above statute while she was an officer of the government, so is therefore LEGALLY ineligible to hold federal office again - per the statute.
It makes no qualification that it doesnt apply to the president. Statutes are written to contain exemptions.
Further if this would disqualify her from all lower offices it would make no sense it would not, for the very same conduct, apply to the highest office over all those shes disqualified from.
