Okay, let’s leave Monica- especially comments about Monica’s appearance out of this. That’s just plain rude.
“Should the President be held to higher standards than us common folk?”
The very question contains the answer. The President is not one of us ‘common folk.’ In fact, he has a great deal more power than any of us common folk. Very few of us can tell the IRS to audit someone. Very few of us can ask the NSA to tap someone’s phone lines. Very few of us regularly have to decide upon matters which determine policy that affects millions of Americans. Very few of us can push a button and have nuclear warheads flying about. And there’s only one person who can do all of that.
The President has much more power than any of us. Therefore, he/she must be held to a much higher standard of moral conduct than any of us.
If I am a pathological liar, who do I hurt? Myself, maybe a few other people, maybe a goodly number if I find a message board, pretend to be someone, and then reveal my pathology later on.
If the President lies to the people, who gets hurt? Depending upon the matter, everyone in his party, everyone in his administration, every in government, possibly every American. That’s a good bit more damaging.
“Shouldn’t human weaknesses be allowed?”
Certainly; if we only elect the perfect, we’d be ungoverned (quiet, Lib).
However, one’s weaknesses should not be a direct effect upon one’s capacity to run the Executive branch; and one should be open and honest about said weaknesses.
To get into specifics, Bill Clinton showed a willingness to break and bend laws that it was his (indirect) job to enforce; and while he had a history of womanizing, he had publicly stated in '92 (over and over again) that he was a faithful husband and would not stray again.
Is it important that the person who runs much of the government not be someone who lies to you constantly? I think so.
