Another apt analogy. Politicians are our patrons not our representatives.
I see you're being extremely obtuse.
If the religious right expects politicians to represent them to the degree that they're presently demanding, then they'd better generate enough votes to keep those representatives in office and elect new ones. If they don't do so, then the politicians who represented them will lose the next election, and a group of politicians who do not represent the religious right will win the next election. More to the point, the politicians who lost the election would not ever trust the religious right again.
