Yea, I remember a couple recent Presidents that talked of being tired, fatigued, needing a refreshing, etc. and they were ridiculled

Let's see, what were their names ... could one have been Mr. Bush? And, what was the response from the left?
Being President is a big job, and you are going to be tired. However, if you used that as a tool against the other side you had better not look for sympathy yourself! Now suck it up, and do your damn job!
