Here’s the process by which Pete Sessions was elected chair of the NRCC:
The Chairman is elected by the House Republican Conference after each Congressional election. Republican Leader John Boehner and the seven other elected leaders of the Republican Conference of the House of Representatives serve as ex-officio members of the NRCC’s executive committee.

It’s apparent we must get involved in this vote, too. After the 2010 election, we must call GOP reps and demand they vote for a conservative candidate to head the NRCC. My vote is Pence.
