...But Banning Gay Marriages is a HUGE issue for Evangelical Christians like myself.
I would say that it's certainly a conservative position to oppose same-sex marriage, but it's a questionable position to support the federal government making the decision for the states. That's ultimately the fundamental problem with the Republican Party in recent years: Abandoning the core State Rights principle that had guided conservatism since the founding of the Republic. Instead of the GOP using its control of government to devolve power back to the States, which was the central priority since the New Deal and the whole reason for the 1994 Republican Revolution, the GOP has expanded and intensified the centralization of power to the Federal government.
That's why Republicans will lose in two days. I don't say conservatives because conservatives have already been routed in Washington. The question is whether conservatism might be resurrected.
