Yes, but a president, or a CEO doesn’t need to know everything. They need a good basic knowledge base, to select staff with expertise in each area and the wisdom to know when to follow their advice.
Herman coulda been one of the best presidents in history (and might yet, 2016 isn’t that far away)...
Let’s put it this way.
He was beating Romney nationally with about 2 months left to go. Imagine if we had all stuck up for him? We’d have our nominee now, and we’d be looking forward to South Carolina, after a big win in Iowa, and Mitt winning in NH.
That was the Democrat line when it was said Obama didn't have the experience, knowledge of governing and other necessary ingredients to be president. And, look what we have now!!
