Seniors vote in much greater numbers than young people and so politicians pay them more attention. The lack of attention paid to younger voters leads the youth to pay even less attention to politics and on it goes in a vicious circle. The only way out of this vicious circle is mandatory voting.
Getting young people to the polls is vital for the future health of Canadian democracy. Many Canadians in their 20s will move into their 30s never having voted and it remains to be seen just how many will start voting.
Of course, what can be said about young and old voting patterns can also be said about other groups as well. Politicians pander to groups who show up to the vote in disproportionately large numbers to the detriment of everyone else.
Mandatory voting will also make elections more about issues. Indeed, anyone who has ever worked on a campaign knows that most of the focus is not spent convincing people to vote this way or that, but rather identifying party supporters and then to pestering them to show up on voting day. Make voting and mandatory and parties would spend more time focusing in on the issues and lot less time and expense tracking down supporters.
