Paul opposes DOMA.
Paul is not running for governor of Kentucky, he is a Senator running for President, yet instead of coming out against gay marriage at the federal level, in the military, federal employment, and immigration, Paul came out for gay marriage, and to remove it from the party platform.
Now we see Paul taking a liberal/libertarian stand on immigration.
Paul opposed DOMA when it was passed (watch your verb tenses, you misleading one you); he also nixed a lot of other seemingly slam dunk legislation. Because he felt it unnecessary. Turns out DOMA was a paper tiger and only added to the uncertainty. It might have made conservatives OVERconfident, if anything. If governments had kept a minimalist philosophy like Paul believed in, in the first place, we’d never have gotten decisions like Kentucky.
