>a politician who does not dedicate his life towards making the laws as perfect as humanly possible (...) clearly does not deserve to be elected.

Oh, sweet summer child. Not attempting to make laws "as perfect as humanly possible" is the least of our worries with politicians!

Most of them dedicated their life actively towards the opposite, to make the laws as bad as posisble: out of ideology, out of being paid by lobbies and monopolies, personal interest, and so on.
