Re: I totally agree with mandatory voting....
Compulsory voting:
Candidate Bloggs stands as prospective MP for the Don't Vote It Only Encourages Them Party.
Candidate Bloggs gets all the votes of those who don't want to vote.
Bloggs becomes MP.
The point is that the introduction of compulsory voting would change the selection of candidates you could vote for - so saying the current crop of prospective MPs are all useless is not a water-tight argument against compulsory voting. There may well be valid arguments against, but that isn't one of them.
