It would no doubt increase greatly, BUT if people don't value democracy enough to go to a polling station, should we make it easier for them to vote? Should we not leave voting to those who really do value our democracy, and perhaps even take a little trouble to inform themselves about the issues and choices?
WHAT WE REALLY NEED TO INCREASE VOTER TURNOUT are "abstain" and "no confidence" options on all ballot papers. At present, the only serious option to express these points of view is to return a blank ballot paper, and these are rarely reported in the media as part of the count unless they are included with the scurrilous returns, so it really does take dedication to democracy to go to the polling station in order to return a blank ballot paper. If these options were available, maybe there would be much less reason for MPs to attribute the low turnout of voters to "apathy".
At the next election it looks as though UKIP might be the nearest that voters can get to a "no confidence" option.
If our politicians spent more time on truly representing their constituents and debating and addressing the facts and details of the subjects which concern them, rather than playing with the words and procedures which they think will most advance their particular party, voters would probably be much more willing to spend some of their valuable time and effort on supporting them, and to listen to what MPs have to say about the concerns and experiences which they have developed in parliament. (Even in the recent Scottish refendum debate, many voters seemed to think that the politicians had failed to give them enough information to make an informed decision, and had avoided discussion of the issues which really concerned people, leaving the voters to learn and have the real debate amongst themselves rather than with those who sought to represent them.) If our democracy is going to to continue to be run by people who have the knowledge and experience of long years of dedicated service, they need to persuade people that they are operating as the voters expect them to rather than operating and voting along party lines. If they do not, I think that there is a danger that future administrations will be lead a dance by representatives voted in by people who barely know their name, let alone the responsibilities which they will be required to bear.
Surely it is logical that there would be pros and cons for all ideals when applied to the real world, and that these should be fully debated and addressed in a framework which will achieve the most appropriate balance in the name of all voters. Otherwise, what is the point of our democracy which people from so many generations have struggled and died for?
