In the first four months of the 111th Congress, 214 caucuses in the House of Representatives registered formally with the Committee on House Administration as Congressional Membership Organizations. Since then, 21 more CMOs have followed suit, bringing the current count of caucuses in the House of Representatives to 235.

Whether you call them caucuses or CMOs, these groups reflect effort at shaping policy in a higher resolution than that of mere party. For that reason, it’s worthwhile not only to track the formation of these caucuses, but also the transparency (or opacity) of membership information. Below I note the names of these 21 newly registered caucuses below, indicating caucus websites and lists of members where available. Where caucus information is not made available to the public, I’ve made note of that, too. I’ve also added them to an accumulated list of caucus web resources for your use as a broader reference.

It shouldn’t be too surprising to see that these caucuses have a low rate of public accounting for themselves. They’re either new caucuses, in which case they need time to self-organize enough to make public report, or they’re old caucuses that are so disorganized as to put off registering until four or five months into the term of a new Congress.
