The problem is that in local elections people still tend to vote on party lines...I'm not voting in our local elections, I've no idea who any of the candidates are or what they stand for. Will I complain about the result? No. I've no skin in the game.
Maybe you should say I should find out, but I'd counter if you're standing for election for some public office, you put the work in if you want me to vote for you.
I've maintained for a long time that local politicians should all be independents...
But failing that, if the party system is maintained then instead of a FPTP in multiple 'wards' all councils should be elected by PR...
