Isenstadt notes that in the past couple of years, GOP-dominated congressional districts have, in many cases, become increasingly white and increasingly conservative. Republican representatives in such districts don't fear a challenge from the political left in a general election. Rather, they fear a challenge from the right in a Republican primary.
This, in turn, has created the incentive for such Republican House members to adhere to a narrow rightwing orthodoxy, while ignoring the party's perceived larger need to reach out to a more diverse electorate outside of the district. In other words, the demands of the individual white conservative district trump the needs of the larger GOP.
Isenstadt further reports on the anxiety of some Republican commentators that GOP congressmen in these hard-right districts are not considering the needs of the party as a whole. Isenstadt's article is linked below.
