A the moment Santorum has no political job.....I think he's looking for a deal with the eventual candidate...i.e., a well-paying, medium profile, political appointment job in exchange for his support in the general election.
This is common practice....and he's probably not the only one in the 2nd tier of candidates to be hanging around hoping for a future deal.
In fact, in most primary elections, candidates with no chance at all file in the hopes of a sinecure in a new administration.
