Politicians in Public and in Private

It seems that politicians never live up to who we would hope they'd be, politics lately has been dominated by absurd over the top rhetoric instead of real debate. 

President Clinton was caught on camera having a candid moment with Congressman Paul Ryan, where he states that he hopes the democrats don't use the special election victory in New York as a signal to do nothing on Health Care. He then tells Ryan that if he needs to talk to give him a call. 

That candid conversation is exactly what should be expected of our politicians, to talk honestly about policy without demagoguing. 

Sadly, just moments later when Clinton was on stage he characterized Ryan's plan would encourage Seniors to "Use less care, and die quicker".

Why can't they just be decent human beings all the time.
