This is nice - I hadn't even considered anybody but Labour/Conservative and this gave some flavour as to where their focuses lie. Disappointed that none of them want to expand LHR though.
And note that "You have 2 choices for Mayor" so you don't have to confine your vote to the usual two big parties for tactical reasons. If you vote for a "small" party with little chance it's not wasted, you have a second choice as backup.
If a candidate of the x tendency gets more than half the first choice votes cast, I think it's pretty-much game over for the anti-x tendency whatever the voting system, or does the math disagree with me?
What makes you think that one of the candidates will get 50% of the vote? And what makes you think that allocating the other voters differently will change that?

Preferential voting: It's a good thing!
