When we can

Build houses and dwell in them; plant gardens and eat their fruit.  Take wives and beget sons and daughters; and take wives for your sons and give your daughters to husbands, so that they may bear sons and daughters—that you may be increased there, and not diminished. And seek the peace of the city where I have caused you to be carried away captive, and pray to the Lord for it; for in its peace you will have peace.
Jeremiah 29:5-7

As Christians, we are first of all citizens of Heaven.  We desire a “better country”.  But we are to be good citizens of our earthly country as well.  We are commanded to fear God and honor the king.  We should not put too much stock in the political process.  On the other hand, if we can use it to promote or defend righteousness, we should do it.  Preach to Caesar when we can; appeal to Caesar if we must.
