Due to extensive losses by conservative and moderate Democrats, another shift in power occurred in the House last night besides Republicans taking the majority. The Congressional Progressive Caucus has replaced the Blue Dogs and the New Democrats as the plurality ideological caucus among House Democrats. For the first time ever, the CPC is larger than Blue Dogs and New Dems combined.

Here are the specifics, assuming every House candidate who is currently ahead stays ahead. That would mean a Republican majority of 243-192, for a net Republican gain of 64:

Here is a finer level of detail that separates out the duplicates, and looks at the five types of ideological caucus members among House Democrats with full voting rights:

As freshman Democrats join new caucuses, and as the Blue Dogs turn to their waiting list, these numbers will change. However, even after those changes, it is highly likely that Progressives will hold on to their new plurality among House Democrats.

Losing the House is painful, and will cause lots of problems for two years (or more). However, it does give us an opportunity to reshape the ideological composition of the House Democratic caucus in a positive way. Imagine if we can retake the House with the CPC maintaining this new plurality.
