Of course not, opebo, but it would be good from the perspective of gay Republicans, or gays who have to live under Republican government.
In an issue-based advocacy situation, the way to win an issue usually is to build support for it within the opposite party such that virtually all of your party agrees with you and the other party's status is something more like "confused" on the issue. Basically what happened to the Democrats on gun control when the Republicans pretty much won the issue.
This will eventually happen with gay marriage, barring some unexpected turn of events, and at that it will be like asking why do some gun owners vote for Democrats?
