Not all Republicans are as spineless as you, squeamishly cowering over the prospect of rocking the boat, pissing off their corporate sponsors, or the nebulous "independent voters". Republicans with your imagination get all their ideas from Democrats, then try to put the Republican brand on Democrat ideas -- like they're doing now with Obamacare, secretly relieved upon hearing the Supreme Court decision. That's how we ended up with dramatically more entitlements and socialism, because of cowards that campaign to the right and then govern to the left -- because, as you say, that's "the reality we live in". You probably have a picture of Karl Rove on your desk.

Rand Paul: Government Should Get Out of the Marriage Business Altogether
http://time.com/3939374/rand-paul-gay-marriage-supreme-court/
There’s nothing spineless about living in the real world.
And there Rand Paul shows that much like his father he has no clue as to why government does what it does. Government has been in the marriage business since the Code of Hammurabi, it ain’t getting out of it any time soon.
