In my opinion, the war on marriage was lost when the churches turned a blind eye to divorce. If we believe in the sanctity of marriage, it needs to be MORE than defining it as "one man/one woman" but also "'til death do us part".
To get there will require changing the culture, not grandstanding on some change to the Constitution.
In the meantime, Romney should focus on his strengths and 0 weaknesses, and not be pulled into the culture war ploy.
Romney sure didn’t consider it “grandstanding” when he signed the pledge that he was for a constitutional amendment that marriage “shall be the union of one man and one woman” and that alone. And it wouldn’t scuttle his campaign, either.
Romney took us for a ride. He signed the pledge because his campaign would have been over had he not signed it.
Now that he has the nomination, he has dumped social conservatives and tossed us under the bus. Romney thinks that he no longer needs social conservatives.
