Is Hillary Clinton Unconstitutional?

Whoops, quick search proves me wrong... a US Senator earns $169,300 (assuming they're not the pro tempore or party leader) - Cabinet positions pay $191,300.  So yes, she'd need a Saxbe fix passed in order to be allowed to serve.

I think you are missing the issue.  It's whether the salary of Secretary of State was increased while Clinton was in office.  It's designed to keep a Senator from getting the pay raised for a nice position, and then getting appointed to that position and benefitting from that pay raise action.

Nope, not missing the issue at all.  If she is to receive the position, the salary paid will have to be reduced to her Senate level in order to stay in bounds of the Constitution.  There is lots of precedent for this, as noted by the fact that the "fix" is named after someone.  The Congress must authorize this, of course, but historically they have based on the fact that the spirit of the article was to prevent government officials from creating high paid jobs and then taking them themselves.

Sorry jimi, that does not appear to be a correct reading of the requirement, according to either the article or the wikipedia link you posted:

The Saxbe fix or simply a "rollback" is a solution to a restriction by the Ineligibility Clause contained in Article One of the United States Constitution on sitting members of the United States Congress changing jobs which are created for them or for which the salary was increased while they were in office.

The issue was the change in salary for the position of Secretary of State, not the relative worth of that versus her current salary.  The salary will be temporarily rolled back to the previous amount that the Secretary of State got.

United States President Richard Nixon wanted to appoint Saxbe as the United States Attorney General from his position as a United States Senator from Ohio following the firing of Elliot Richardson in the Saturday Night Massacre in 1973.^[1] Saxbe had been a Senator in 1969 when the Congress passed a pay increase from US$35,000 to $60,000 for Cabinet members.^[5] Congress eventually allowed the appointment when it accepted Nixon's request to lower the attorney general's salary to its pre-1969 level. Saxbe went on to serve as Nixon's fourth and final Attorney General.^[6]

From the Saxbe fix link above:

In James Madison's notes at the Constitutional Convention, there was fear of members of Congress creating new jobs or giving raises to existing jobs, and then taking them for themselves. Madison viewed creation of offices, and increase of salaries as one of the greatest fears of corruption of legislative service.

It's not just a branch issue.  It's an issue of the legislative branch passing legislation to make cushy executive positions for them to then move into after Congress.

Touche Adam.

However, the Constitution doesn't make it clear that the increase had to stem from an actual vote of the potential candidate.

It seems like the spirit of this restriction would require the candidate to have been able to vote on the pay raise.

This issue has its own paragraph on the Saxbe fix page. 

It is unclear whether the salary would need to be reverted to its pre-2000 level or pre-2006 level.^[12] However, United States Department of Justice memorandums outline official opinions by United States Attorney General that "the Ineligibility Clause covers only increases during the term that a Member of Congress is currently serving."^[13]

Actually, her expertise on Russian affairs could be useful, if not directed by George Bush.  She is a world renowned expert.

The Secretary of State is required to present the President's position.
