Spheres

I was at a church gathering last sunday night where we watched some of Focus on the Family's "The Truth Project" (which is really good by the way.) One of the things the person teaching did, was he had a graph which had several different colored spheres. One said "God", another said "Family" another said "Church" another said "Labor" etc. etc. His point was that we need to be careful not to confuse spheres...in other words, just b/c God says "Wives, submit to your husbands" in Ephesians (a command relevant to the sphere of family) or, in 1 Timothy, "I do not permit a woman to teach or have authority over a man", a command relevant to the sphere of Church, does not mean that man cannot work somewhere just because he has a woman supervising him, or whatever. (Which doesn't involve the sphere of family or church, but of labor.)

He then made a passing reference that in his study of Scripture, he hasn't seen any passage that would indicate that it is unbiblical for a woman to be in authority over a man in the area of labor or, incidentally, in politics. Obviously this is relevant to us now, since the thought of Hillary Clinton being president may soon become a reality.

Now, one could argue (which I'm not going to right now) that it would be unbiblical to vote for Hillary b/c of her stance on abortion or some other issue. However, my question is; is it unbiblical to vote for Hillary b/c she is a woman? This isn't a chauvinistic questions, I simply want to know if you all think it's biblical for a woman to be in authority of an entire nation.
