I feel for you, man.  I have a wife who is a rabid supporter of our President and love her to death for it.  But I do have a dumb-as-fuck sister in law and brother who are POTUS haters that I just ignore nowadays.  In their place, I have 3 sisters who are supporters of DJT and so do their husbands.  Just the DAF brother and sister-in-law are troublesome.
