Rick Santorum is in...

...the catbird seat. If the former senator from Pennsylvania stays in the Republican race it could help Mitt Romney by dividing the conservative vote. If he drops out sooner rather than later, it would clear the field for Newt Gingrich as the only alternative to Romney.

You don't suppose Santorum is negotiating right now for a high-level cabinet post in a future Gingrich or Romney administration, do you? How about the VP slot?
