There is always a political test for every political job. To deny that is to deny reality. I wrote that it was important to me, I don't want to support an apartheid regime, and hiring that guy to my government would be, in part, supporting the idea of apartheid. But in reality, I am one vote every four years...
Just expressing my opinion. Surely there are political opinions you would object to in a candidate. 
There is also a science test to the science job, so neither Madonna nor I would qualify.
