Hum, so Santorum may have good reason not to pack it in. Now, the RNC would have to grant a waiver for this change which seems unlikely. But as the Caller reports:

Nevertheless, the mere idea of changing the delegate math could have an impact on the race, Bellow explained.

“Just the simple idea that we might be changing to winner-take-all will likely already have an effect on the race because it could boost the spirits of the Santorum people in Pennsylvania,” Bellow added. “If Santorum does well in Pennsylvania then that could keep him in the race till Texas or later, thus creating more of a chance for a brokered convention if Romney cannot close out.”

Bellow made it clear, however, that although he is a Rick Santorum supporter, he has always been in favor of winner-take-all. He said that some SREC members in favor of a rule change are not Santorum supporters, but are primarily concerned that Texas has a strong voice.

“We are just tired of being ignored. This is about making Texas relevant instead of having candidates ignore us every election,” he explained.

My gut tells me this sounds like a last chance gasp.
