Jeb took a more nuanced view stating: “Guided by my faith, I believe in traditional marriage. I believe the Supreme Court should have allowed the states to make this decision,” Bush said in the statement. “I also believe that we should love our neighbor and respect others, including those making lifetime commitments.

It is now crucial that as a country we protect religious freedom and the right of conscience and also not discriminate.”
