Where the GOP Suicide Caucus Lives

In short, these eighty members represent an America where the population is getting whiter, where there are few major cities, where Obama lost the last election in a landslide, and where the Republican Party is becoming more dominant and more popular. Meanwhile, in national politics, each of these trends is actually reversed.

.. In previous eras, ideologically extreme minorities could be controlled by party leadership. What’s new about the current House of Representatives is that party discipline has broken down on the Republican side. On the most important policy questions, ones that most affect the national brand of the party, Boehner has lost his ability to control his caucus, and an ideological faction, aided by outside interest groups, can now set the national agenda.
