If Gingrich really drops out after IL or LA, and endorses Santorum, maybe he could even convince Sheldon Adelson to write a 50 Mio. $ check for Santorum for the ultimate battles in NC/IN/WV and then later TX and CA. This would badly damage the Romney money machine (unless he writes himself a check for 50 Mio. $).
Adelson HATES Santorum...
Equally, if these numbers are in fact correct... and they look reasonable, Romney should be worried about Santorum's underpolling in TN, MS and AL.
Maybe he hates Romney more ... ?!
He donated several million to Gingrich's PAC for the expressed purpose of hurting Rick.
