As long as he/she does not legilsate their biblical morals into law, there shouldn't be an issue here.
I'm not aware of any theistic belief system that does not require its followers to adhere to doctrine in all aspects of life. In other words, if a christian truly believes in their faith then they are required to follow the tenets of that faith in all circumstances. So, if a christian is elected president then they have a dilemma. Either do the job in the manner that those that elected them want it done, or do it in the manner that they believe god wants it done.
I witnessed this first hand when I attended a christian business school. Each class incorporated christian principles into the curriculum in the form of a "christian worldview" assignment in which you had to deal with a scenario where the correct business decision was not entirely in alignment with christian principles. The "correct" answer was invariably considered to be the one that put god before stakeholders.
Simply put, a christian can not avoid legislating their faith (and still be considered a good christian).
