So you are a bleeding heart liberal and your sweetheart is die hard conservative. Can this relationship work? YES! But each of you must practice, civility, patience, respect and self control.
There is no reason to argue every policy with your sweetheart. Save those political debates for friends and family. Pick you battles with your partner, when it comes to your differing views. Isn’t that what you do anyway? When two people love one another, they look for ways to connect.
Studies show that conflicting religious beliefs are harder to overcome than conflicting political views. However if a couple is on the opposite side of the fence on both these issues, all is not lost. Be curious about what your partner thinks and believes without trying to talk them out of it. Be respectful and always use humor. Keep in the forefront that your relationship is what is important.
