Culture, what you believe, what you value, how you live matters. Now, as fundamental as these principles are, they may become topics of democratic debates from time to time, so it is today with the enduring institution of marriage. Marriage is a relationship between a man and a woman.

Men and women of every faith and good people with none at all sincerely strive to do right and lead a purpose-driven life.

When my mom ran for the Senate, my dad was there for her every step of the way. I can still hear her saying in her beautiful voice, 'Why should women have any less say than men, about the great decisions facing our nation?'

Mom and Dad were married 64 years. And if you wondered what their secret was, you could have asked the local florist - because every day Dad gave Mom a rose, which he put on her bedside table. That's how she found out what happened on the day my father died - she went looking for him because that morning, there was no rose.

My mom and dad gave their kids the greatest gift of all - the gift of unconditional love. They cared deeply about who we would be, and much less about what we would do.
