That brings up a good point, though. What will the next wedge issue be?
Personally, I'm thinking transgender issues, considering they're shadowing gay issues now just like gay issues were previously shadowing racial issues.
Of course, abortion isn't going away any time soon either.
I think there are three possibilities:
1. Operation "Woo the Latinos" works, and the GOP gains a new power base, relying on its usual platform.
2. The GOP doesn't change its policies, or the Latinos continue to vote Democrat, ushering in an era of Democratic dominance.
3. The GOP bites the bullet and jettisons its social conservatives, focusing solely on reducing the size of government. GOP remains a viable party, although some social conservatives either flock to a fringe party or start a new one.
