This is a tactic that I regularly emply while playing a faction with absolute Monarchy. It quickly allows me to fill up all the ministerial spots with at least 5-6 star administrators.

Problem:

1. You are unhappy with at least one of your ministers or are simply on the lookout for better men.
2. The five men in the pool of candidates are not very spectacular.

Solution:

Completely flush the pool of candidates.

1. Single out your worst minister. His seat will be used as a rotating chair.
2. Out of the pool of candidates choose the guy best fit (or least unfit) for that seat.
3. Filling the rotating chair with the men from the pool of candidates, with the candidate of choices being the last guy to fill the seat. Since you're an absolute monarchy, it can all be done instantly, and now you have a completely vacant pool of candidates. Chances are that out of the 5 new candidates that you'll get in the following 5 years at least one will be better one of your current ministers, in which case *that* minister's seat will become a rotating chair.

This trick makes absolute monarchy the best form of government.
