The party is deciding
A group of studious convention wonks are keeping an eye on the endorsements made by superdelegates to the 2012 Republican convention. This group is a pretty good proxy for Republican Party elites -- or, at the least, for the elected wing of the Republican Party’s elites. Seth Masket graphed the commitments so far, and as you can see, Romney is running away with them.
That said, there are about 117 superdelegates who haven’t committed to a candidate, so if Romney falters and another candidate picks up steam— unlikely as that looks now — there’s plenty of room for the superdelegates to back him up. This is a good time to read “The Party Decides,” if you haven’t done so already.
