On a tangentially related note, I like this op-ed from Bill Kristol about it being alright for the GOP not to have an official leader or agenda yet. In Let 1000 Republican Flowers Bloom, he argues the times call for political entrepreneurship, not conformity:
Congressmen used to looking to the White House for guidance or approval--or fearing disapprobation--should show some healthy ambition and unleash their inner policy entrepreneur. Backbenchers need to come forward with heterodox ideas. There should be vigorous debate. Disharmonious disarray is in the short term much less of a danger than a false and stultifying unity.
