It may not be all Wubble U’s fault. He may just have been poorly educated and is now too ignorant of his lack of scientific knowledge to change.
One of the defects of democracy is that we usually have quite ordinary persons as our leaders. Sometimes this doesn’t matter; their particular defects don’t bear upon public affairs, or the times are sufficiently placid that it just doesn’t matter that they drink, or play too much poker, or cultivate friends of doubtful character, or whatever.
These are not such times. The President’s ignorance of science might have remained a private matter, but he chose to speak on the subject of evolution and “intelligent design.” This is a great pity.
