It seems to me that the meaning of the Constitution is dependent upon how it's interpreted. Who, then, has the final word in how it is interpreted?

Thomas Jefferson:

"On every question of construction (of the Constitution) let us carry ourselves back to the time when the Constitution was adopted, recollect the spirit manifested in the debates, and instead of trying what meaning may be squeezed out of the text, or invented against it, conform to the probable one in which it was passed." letter to William Johnson, June 12, 1823, The Complete Jefferson, p 322

The SCOTUS has the final word on interpretation of the constitution, however, they refused to hear this case.

The Constitution is a fairly short document, and is not beyond the comprehension of any educated person. The assumption that many make is that it is too complicated for any but legal experts (read lawyers) to interpret. These people are then willing to accept the most ridiculous and improbable pronouncements from supposed “experts,” known as the members of the Supreme Court.

As we have seen in the past, the Supremes have political agendas and will impose these agendas on the people if they are allowed to get away with it.

The answer to your question is: the final arbiters of the Constitution, as well as every law, are the people. It is the Supreme Court, not just the legislature that reads the election returns.
