I am all for banning parties altogether. What we need is objective people without party agendas that can work together to govern. As I keep saying, chuck the crap out and keep the good from each rather than choosing both the good AND the bad from one.
It's not the parties that are the problem, it's the politicians. In the old days the parties had a philosophy that was closely followed, but now because politicians lie so much that is all by the boards- the ones who squander money pretend to be conservatives and the cheap bastards pretend to be liberals. And they are all striving to be more rotten than the other guy to get more votes to ensure their tenure, so they can qualify for bigger pensions and other benefits from the trough.
