We don't like to give them our money, so they have to source funds in questionable ways.
What if all those questionable ways of raising funds were legislated out of existence? Elections would be quieter for a start; would that be so bad?
Some people think political parties should be funded out of taxes? Really? I can see that causing huge resentment.
What if the existing parties went bust? Would we miss them? Would new ones take their place?
Is democracy conceivable without political parties?
