How long has the Abu Qatada been going on ?
Local council elections only get about 20% turnout, should we abolish the councils too. (maybe not such a bad idea !)
Maybe I don't disagree with you, and dreadful handwringing it may be, but it is the case it is happening.
At this point the only influence we can exert is, as you alluded to earlier, by being positive/pro-active.
Ignoring the elections will not make them go away, there will be a PCC.
Maybe if...
Doesn't matter that nobody asked your opinion about whether it should happen, the fact is it is happening.
Not voting isn't active objection as no-one knows you are objecting, spoiling your ballot paper however ........
Size of turnout doesn't matter for other elections either, nothing unusual...
It might be pointless, needless etc but it is happening.
If you have no interest in who gets the job, fine, just don't complain when they do things you don't like. You are not intrerested in the position so you are not interested in what happens.
Conversely you could have your say.
