From Will Wilkinson:

Can they help it? Well, there simply aren't enough older white, nationalist, conservative Christians to make up a durable electoral majority. The GOP must become younger and/or browner or reconcile itself to perpetual loserdom. Yet a slightly more socially moderate, slightly more multicultural Republican Party is by no means impossible, and could even conceivably dominate. I'm confident the GOP will get there sooner or later. Sooner if a leader emerges with the political chops needed to persuade older, white, religious conservatives that in their big, Christian, American hearts they have all along affirmed exactly what the party needs to win. Or…they can do it one funeral at time.
