#VoteBike - 2012 London Mayoral elections

^This if you are that dissatisfied with the two main candidates then your first vote should be someone who isn't one of them. It would appear that a lot of the electorate have had enough of Boris and Ken but nothing will change if one or other of them are their first vote on the ballot paper.

The worst case scenario is that if this is a close run election between the front runners that they will potentially be the Labour and Tory candidates at the next mayoral election.

This.
people in this country don't really get how anything that isn't a first past the post voting system works. They go into the ballot box thinking of one candidate only realise and decide upon the second at the booth.
It's not a given that it must be a Tory or Labour victory either. After all, Ken's first term was as an independent against Labour's official candidate Frank Dobson.
