HuckPAC's Healthcare Threat

Mike Huckabee's PAC, HuckPAC, has issued the following warning: 

Huck PAC will not endorse any Republican candidate that votes for the government takeover of health care. And if we have endorsed your campaign, and you vote for this monstrosity of a bill, we will revoke your endorsement immediately.

Let's suppose that HuckPAC-endorsed candidate Les Phillip of Alabama announced that he would support healthcare reform and Huckabee revoked his endorsement: would HuckPAC then reimburse Phillip for the tens of thousands of dollars that Huckbee's endorsement has already cost his campaign? 

Just curious.
