From my limited experience these things are held having given the public next to no information upon which to make a reasoned judgement so of course few bother. Those that do are probably voting blind based on the cut of the candidate's jib. It's not that folk don;t give a rat's ***, it's that it is a vote too far, unless there is a lot more effort made to distributing information. It's bad enough to know who is worth voting for in local elections (none of them want to do what I wish them to) without police ones too.
