Why don't conservatives trust Mitt Romney?

Exhibit A.  The Boy Scouts, an organization that has withstood the homosexual juggernaut for decades, gets blindsided by Mr. Romney who takes a stand against their belief that men who are sexually attracted to other men ought not share close sleeping quarters with teenage boys.  Once again from the top: the GOP has only and ever begrudgingly bought into social and religious conservatism, largely due to Ronald Reagan's legacy.  A growing number of GOP pols would gladly and gleefully jettison all that pesky social conservative garbage, opting instead to continue their priority of eliminating taxes and regulations for large, multi-billion dollar corporations.  Buyer, beware.
