Members of the Republican National Committee are in Los Angeles this week for a three-day retreat. They're here to focus on the one thing that really matters to political parties: How to win elections.

But there's a lot of disagreement on how the GOP can, and should, do that. Differences over issues such as immigration and same-sex marriage are causing some schisms in the party. An even more thorny issue is how to select candidates for office that have the best chance to win.

Here to discuss some of the challenges the Republican Party leadership is facing, and how they might tackle them is John Feehery, longtime GOP strategist with the public affairs firm Quinn, Gillespie and Associates.
