It's often said that the problem with political jokes is that they sometimes get elected. In Canada's recent elections a candidate won a Quebec constituency without even visiting it.
She lives 300 km away, speaks little French and spent part of the election on holiday in Las Vegas. She won because Quebec voters switched en masse to the New Democratic Party. The separatist Bloc Québécois party plunged from 47 seats to only four.
Not so long ago the Canadian Liberal Party was in government, but it ran third nationally behind the NDP. Voters surprised the pundits by giving the Conservative party a majority while reshaping the opposition completely.
Canadian politicians have reason to fear voters. A previous Conservative government was reduced to only two seats after an election.
It's healthy for democracy when voters feel free to change parties. In our elections it's been fascinating watching the ANC as it realises it can no longer take its supporters for granted.
President Jacob Zuma has tried to quell dissent over candidates by saying this can be fixed after the elections. This is laughable and indicates a certain desperation as communities threaten to abstain or vote for other candidates.
