Can't Govern By Biblical Principles?

My response to Sharon Martin's "Open Letter To Sen.-Elect Lankford" published in The Oklahoma Observer on Nov. 11, 2014:

Everyone governs by a set of principles whether Biblical or not. Ms. Martin's principle is that one has "every right to live your life according to those principals, so long as you don’t hurt anyone."  By what objective standard does Martin's principle get to govern but Lankford's does not? 

Further, Martin claims that Lankford's various positions violate his Biblical principles (e.g opposition to the Affordable Care Act and minimum wage) arguing that her position is actually more Biblical. Martin advocates governing by her more Biblical principles but criticizes others trying to "govern according to [their] Biblical principals".  Her argument commits suicide.
