deception

All Politicians Lie, it is said.

   But should they and are some liars just too much?  Too full of deception they shouldn't be trusted with a public trust.

For example in 2008 both Obama and Hillary affirmed that marriage was a one man one woman deal. They both have been reported to have had gay affairs. They now forcefully speak on gay rights as human rights.

When someone knows that they could never get elected unless they lie and get in office then promote an agenda directly against what they know they could not get away with prior to the election is that administration based on a grand deception?

Does this fundamentally undermine democracy itself? These are valid questions. Ones that should anger voters.
