I am actually hoping a social conservative gets nominated, annihilated in a blowout election, and forever discredits that wing of the party.
I think some swing voters are able to appreciate someone who speaks their opinions honestly, even if they don't completely agree with them. When the candidate (Romney, McCain) is afraid to take a position out of fear of alienating voters that are 90% Democrat and are not swing voters, it is the equivalent of a downward spiral in polls, you're focusing your GOTV on voters who are 100% invested in electing Democrats, and completely alienating voters who you absolutely need to win.
I'm not saying, all the Republicans need to do, is nominate a social conservative activist, and then the White House is in the bag. I'm saying that they need someone who relentlessly focuses on the three legged stool of the Republicans and understands that hyper-social-leftists aren't going to be open to voting Republican. Ohio, Pennsylvania, and Florida should not be cast aside in an attempt to run up the percentage in the Castro or the West Village. It's a ridiculous strategy on part of the GOP - they're more obsessed with the gay vote (what, 5% of 2012?) than any other demographic.
Romney was obsessed with the gay vote? That's news to literally everyone who witnessed 2012.
