That's because the judicial branch was design to be a-political.
While I enjoy reading Posner's opinions, I think he should run for office if he wants to be in the political spotlight. I don't want judges creating and pushing new political theories. I want them to spend their time and energy understanding the laws created by legislators and interpreting those laws as best they can through the filter of the Constitution.
Whenever a judge decide something, it usually make me like them.
In fact, Americans trust their judges more than their politicans and bureaucrat. http://www.gallup.com/poll/143225/trust-legislative-branch-f...
