It seems pretty obvious that there's a huge empty niche open for somebody to come along and embody a very old type of conservatism: Green Eyeshade Conservatism. Sharp Pencil Conservatism.
Picture a suspicious, flinty old bastard who adds up all the numbers twice and makes sure nobody is pulling a fast one with other people's money. He doesn't care whether the folks playing fast and loose call themselves "government," "private enterprise," "NGO," or some monstrous hybrid.
It's not been a popular role lately, so I don't know who would be ready to step into it. (Maybe California state senator Tom McClintock if he could get himself elected to statewide office in 2010? But that's a big if.)
