HRC organizer John Gomez spotted Cindy McCain at a Staples in Phoenix, Cole-Schwartz wrote in an e-mail. "He talked with her about our efforts to pass ENDA, and she shared her support for the bill," Cole-Schwartz said, adding that she signed the postcard and addressed it to her husband.
At the moment, it does not appear that Cindy McCain has changed her husband's mind. In an e-mail, McCain's spokesman Brian Rogers wrote, "Senator McCain enjoys and appreciates having discussions on the important issues of the day with all the members of his family, and he respects their views."
The measure, which bars discrimination against gay, lesbian, bisexual and transgender Americans, stands a better chance of passing the Senate than the House. The Senate failed to pass a similar bill by a single vote in 1996, though that measure did not include gender identity safeguards.
