Ed, it might reflect current thinking if the poll included a 'none of the above' option.
I don't think at all that I'm alone in despairing of party politics, and to engage ordinary people in political processes there needs to be a way to enable a feeling like mine to be voiced.
As it is, you can choose to vote for a group you don't really go along with , or not vote at all. Or spoil your vote, which is daft.
I feel strongly that people should vote as good people died in the past for this privilege, but the current system is plainly not encouraging ordinary non-fanatical people. I know of many folk under 30 who have never bothered voting.
