Tampa (CNN) - A man hurrying to catch the light at a corner in muggy downtown Tampa carries a book with a rainbow of color on its cover.
Its title stands out, especially here, where the Republican National Convention has officially accepted a platform that a New York Times editorial called "more aggressive in its opposition to women's reproductive rights and to gay rights than any in memory."
The book is "A Fundamental Freedom: Why Republicans, Conservatives, and Libertarians Should Support Gay Rights."
Ted McCormac is a precinct committee person for the GOP in Bradenton, Florida, and the father of a gay son. He picked up the book at a brunch co-hosted by the Young Conservatives for the Freedom to Marry and the Log Cabin Republicans - two of a small number of visible LGBT-supportive Republican groups at this year's convention.
Individual members of the Log Cabin Republicans have attended previous conventions, but this year marks a first for the group: It was invited by the Republican National Convention committee to participate in the convention itself. In addition, there are many high-profile, gay-themed events this year, including the brunch McCormac attended. "I've never been to an event of theirs, but people clearly went out of their way to be nice to me," McCormac said, with a catch in his voice. "It means so much since I'm kind of new at this."
