is Santorum being starved for money by the RNC? if that case can be made, then of course you are correct.
Frankly, I don't know. But I can't understand why the RNC would spend money in support of Chaffee in the primary if there are any Republican candidates anywhere else who might benefit from these funds in the general election.
Besides which, if $X improved Chaffee's shot at winning by 10 pts, that's not as valuable to the party as improving Santorum's odds by 2 pts. (Proportion may vary due to individual preference, but you get my point).
Santorum has 10 million cash on hand, his opponent Casey has 5 million.
