Factions in the Republican Party (Jon MacKay)

The image above shows members of the United States House of Representatives. Using data from interest groups we isolate three distinct factions within the Republican Party.

We’ve finally submitted the last materials for our up-coming publication in Legislative Studies Quarterly. This paper has been a long time coming!

Here’s an abstract of the paper:

Congressional parties are commonly viewed as unified legislative teams, but recent intraparty battles have revealed serious ideological divisions within the House Republican Party. Using annual ratings from nearly 300 interest groups, we estimate the ideological locations of Republican legislators in order to map their party’s factional structure. Based on the distribution of interest-group support from 2001 to 2012, we detect three Republican factions that we characterize as worker oriented, pro-business, and ethno-radical. We find that Republican leaders block bills by legislators in the worker and ethno-radical subgroups, and that they advance bills by members in the corporate faction.

You can a little more about it on my new ResearchGate profile page. You can also get the most up to date information on my web site.

Here’s the working paper version from the Saïd Business School’s SSRN working paper archive.

Now for a little extra bonus…
