Family Voting

Now that I'm old enough to vote, I've been spending a fair amount of time looking into the various measures that are on the ballot for my home state of Oregon. As I was researching, I thought I should call Dad and get his opinion on one of said measures, the thought dawned on me "What if I don't agree with my dad on one of the measures, do I really want to have the effect of nullifying his voice, by voting contrary to him?" That begs the question, what will I do if I disagree with my dad, what will I do? As far as I can tell there are three possible options:

Option 1: Copy how dad votes, and just hope for the best.
Option 2: Thumb my nose at him and vote the way I want to.
Option 3: Work through the issues, and try to come to resolution.

Now, obviously option one and two are absolute non-options (if it were possible to burn bits and bytes, number two at least, should be burned). The third option is the one that I want to elaborate on, which I will procede to do, thusly.
In the unlikely event that we're unable to come to agreement on an issue on which I have a scriptural conviction, I feel that I would have to, as respectfully as possible, cast my vote based on biblical principle.
Thankfully, I don't expect the above situation, and I think that the most desirable outcome would be that through respectful and loving discusion, one of us would be convinced of the others position, thereby bringing harmony.
However, where that isn't possible, I feel that it would be my duty, and my honor, as my fathers son, who, not being married (and thus, head of my own household), is still under his direct authority, to vote the same way as he does, so long as doing so would not violate scripture (i.e. pro-life vs pro-choice). Even if he did not require me to do so, I would not relish the thought of negating the effectiveness of my fathers voice. Praise the Lord that He gave me such God fearing parents, and I think that this voting season will go quite smoothly.

Semper Reformanda!
