If we had PR, I would consider policies when voting. But at this point, even if I agreed with all conservative policies, I would not trust them to implement any of them. So my main consideration is which party has the best chance of beating the con artists in my area, not which party has the ‘best’ policies.
Under FPTP there is not much use for this site. And while I believe, until proven wrong, that this site was created with the best intentions, the cynic in me thinks it could be a conservative plan to encourage a split in the votes for their opposition.
