I'm sorry to be the one telling you this, sprintcyclist, but it's not actually an original idea of yours.
This political style was actually already around in the 1800's in Australia, where political parties did not exist, and 'nobles' were the ones who were in parliament. But the difference was, they were not paid to do this, which is why only rich people ran for office back then. It was only when politicians started being paid that working class people started trying to get elected and started being politicians.
There was good points and bad points about this system of Government:
Good Points: 1) Politicians could make moral judgements for themselves and were not confined to follow party lines of thought.
2) Were not that corrupt.
Bad Points1) Hardly anything was achieved, as people would disagree on almost every issue and a conclusion was never reached by a majority.
Political parties were basically just an evolutionary step. It's basically just a bunch of people with similar interests and beliefs who decided to bond to win power.
Ever watched 'survivor' the TV show? There's a good example.
