Huckabee becomes the second potential candidate to advocate repeal of the repeal of the gay military ban if he became president. Pawlenty was the first. Even more worryingly, Huckabee seems to believe that the military should decide its own rules, rather than be subservient to the civilian government.
Huckabee, for all his bonhomie, is a radical Christianist. And the GOP may not be using the anti-gay card to win elections any more ... but that doesn't mean that they won't, if given power, do all they can to restigmatize and discriminate against gay citizens because they're gay. And in the primaries, there is already a competition to be the most anti-gay candidate.
