No, he has not. He continues to support the gay agenda to degrade marriage.
6-13-2011 debate went to great lengths to say it was a state’s right.
He did reverse that on 8-11-2011 because what one state recognizes in this regard ties the other states’ hands. That’s the trouble. He is saying good things (now) more often than not, but he has a record of saying what he thinks people want to hear. He’s been all over the place on gay marriage (destroying marriage) in the last year.
You obviously didn't read his record or the conservative leaders who worked with him and said "In fact, the entire nation has benefited from his socially conservative, pro-family actions in office. As we explained earlier, his leadership on the marriage issue helped prevent our nation from being plunged into even worse legal turmoil following the court decision that forced “gay marriage” upon our Commonwealth."
There isn't a single office-holder who has been in this fight longer and who worked harder to defend marriage.
Those who turn this reality upside down can be shown the facts, but it's up to them to have the decency and honesty to recognize it.
