Speaking as someone who votes conservative, there is not a Christian party. The US essentially has a two party system with not a lot of nuance. For example, if someone's against abortion, then for the most part their only option is to vote for the Republican party, regardless of whether or not they agree with other things on the Republican platform, and vice versa.
It is not as though on party wants to see refugees treated with dignity, the poor fed and housed, and the sick cared for without risking bankruptcy while the other doesn't, but rather there is a disagreement about the best way to go about doing this and what is the most effective use of resources. There are ways of helping that have done more harm than good, so we should not simply be in favor of anything that throws money at the problem. For example, foreign aid can do damage to foreign economies, increase state corruption, postpone necessary reforms, and create wrong incentives. We should be willing to evaluate whether something is effectively aiding the people who need it the most, whether it is easy for people who don't need to take advantage of it, whether it is fostering independency or dependency, whether it is the most effective short or long-term solution, or whether it is more effective to be handled privately rather than at a national level.
Yet the stranger in the land is oppressed, turned away in their poverty, refused the same justice that the citizen has a right to, they go hungry, do not receive medical care without risking bankruptcy, and if the only reason these things are as they are is a disagreement about how to reverse them then why not stop doing them and then sort out how to pay for it or whatever other details are the differences between one party and the other?
But I raised these matters as examples only. The heart of the matter is encapsulated in a kind of doxology that saint Paul wrote in one of his letters, it is a reflection of our Lord's sermon on the mount from Matthew chapters five through seven, and it reads thus:
If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal.
And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but have not love, I am nothing.
If I give away all I have, and if I deliver up my body to be burned, but have not love, I gain nothing.
Love is patient and kind;
love does not envy or boast; it is not arrogant or rude.
It does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrongdoing, but rejoices with the truth.
Love bears all things, believes all things, hopes all things, endures all things.
Love never ends.
As for prophecies, they will pass away; as for tongues, they will cease; as for knowledge, it will pass away. For we know in part and we prophesy in part, but when the perfect comes, the partial will pass away. When I was a child, I spoke like a child, I thought like a child, I reasoned like a child. When I became a man, I gave up childish ways. For now we see in a mirror dimly, but then face to face. Now I know in part; then I shall know fully, even as I have been fully known.
So now faith, hope, and love abide, these three; but the greatest of these is love.
(1 Corinthians 13:1-13 ESV)
Christianity as a lived experience ought to bear one fruit above all others, love for our neighbour as deep as our love for ourselves.
