Presidential candidate stances on gay marriage
On the Republican side, Ron Paul thinks the federal government should have no role in deciding what a marriage is, and McCain is personally opposed to gay marriage but thinks it's an issue for the states to decide. The rest of the Republicans are opposed to gay marriage and civil unions. Rudy Giuliani has in the past been more gay friendly, but is now pandering to the homophobic base of the Republican party. So who knows how he'd act if elected.
The Boystowners site notes that Republicans feature their anti-gay marriage stances prominently on their websites, while Democrats do not feature their pro-civil unions stances in a similarly prominent matter. This is disappointing.
