We get the leaders we vote for, at least. It is perfectly possible for people to be elected as an independant. if it possible to do so without a prominant sngle issue campaign, or huge satisfaction with the party that has dominated that area for decades, I don't know.
Having a decent number of independants in parliment would be good for democracy, and might even promote some better though out bills.
