When you marry someone you also marry the relatives and friends. You meet them when its too late. Choosing a prez is like that isn't it?

You have ZERO idea whom that person will choose for cabinet members and administration positions other than the veep which you already knew going in. Some choices can shock you and  bring you to the brink of despair and drive you bonkers. Some relatives/friends of said spouse can do the same. You can always get a divorce of course. You can dump a mate a lot easier/quicker than you can dump a prez. Sadly.
