You just say it as you’ve said it here. “You are not welcome for Christmas because you are not voting Republican”
Then you should probably pray about it some and read your bible to see what Jesus said about love and forgiveness and kindness to all people. If Jesus could forgive sinners, heal lepers, and minister to prostitutes and beggars, perhaps you can find something in his example to soften your heart towards your family.
Politicians come and go. Family is forever. Politicians will not come to your house for holidays. Politicians will not give you grandchildren (unless it’s Herschel Walker, I guess). Politicians will not comfort you in your old age or provide for your comfort. (In fact, Republicans are trying very hard to remove federal old age benefits and federal health coverage for retired people…why are you voting for them, again?)
Your grudge against your own flesh and blood seems petty, mean spirited, un-christian, and short-sighted. I urge you to reconsider. The holidays are a time for family and love, sharing your blessings with people you care about. Perhaps you can ask that the family not discuss politics at your gathering, and that might be a good compromise.
