Discussion of cabinet-staffing yields:
You don’t want the camel pissing in the tent.
True, but not unproblematic. There are of course two tent metaphors: better inside pissing out than outside pissing in, and the problem with letting the camel get his nose in the tent is, pretty soon you get the rest of the camel, too.
And these metaphors have, it seems to me, opposite implications for cabinet-staffing.
