(CNSNews.com) - Democratic Vice Presidential Candidate Sen. Tim Kaine says that he changed his mind on the issue of same sex marriage, because when the Virginia legislature tried recognizing that a “marriage is between a man and woman” they were “doing it to try to make the state a hostile place.”

“You know, on marriage equality I got tell you, in my first year as governor my legislature decided to put one of those same-sex -- marriage is between a man and woman issues on the ballot and the more I listened to the reason they wanted to do it the more I realized I can't be with those guys,” Kaine told Good Morning America on Thursday.

“Because they're doing it to try to make the state a hostile place for people I care about, and so I campaigned against the marriage amendment in '06 and been over on the side of, wait a minute, we just can’t discriminate against people. I'm a Progressive in the south and that may be different than being a Progressive in Vermont or a Progressive in Oregon.”

Kaine’s comments came after the show played a 2005 gubnatorial campaign radio ad where Kaine said, “I'm against same-sex marriage. I'm conservative on personal responsibility, character, family, and the sanctity of life. These are my values and that's what I believe.”
