Larison ponders the phenomenon:

Everyone who is voting Obama to punish the GOP thinks that there is some small chance that the GOP might change its ways. The diversity of views among Obamacons reflects how many different future directions are expected, guaranteeing that many will be disappointed, but it also reflects how badly the GOP has failed on multiple fronts that it is simultaneously losing so many prominent and obscure Catholic pro-lifers, libertarians, foreign policy realists, moderates and small-government conservatives, among others, to a Democratic nominee who genuinely is the most liberal of any they have had since 1972.

Under normal circumstances, a vote for Obama ought to be unthinkable for almost all of the people on the right who have endorsed him, but the GOP has failed so badly that it has made the unthinkable mundane and ordinary. It’s reaching a point where the report of another Obamacon endorsement is no more remarkable than when the leaves start falling in autumn. Far more important in the aftermath than coming up with new and amusing ways to mock the Obama endorsers is an effort to understand and remedy the profound failures that made this phenomenon possible before a major realignment does occur.
