"We really should try and elect honest, competent, morally and ethically principled political leaders, shouldn't we? Not simply hand power to self-serving morons in the hope that they might embarrass themselves." ???
No politician would ever get elected then especially since you included "Honest" in fact any one of the points you mentioned would exclude all Politicians !
Yeah I have great faith in our political system right after we have proportional representation voting system, but neither of the top two would ever want that - would they so no matter how much better it would be as it wouldn't be in their self-interest !
