So the results are in. After spending an entire month campaigning on a cut to his council tax precept, Boris Johnson now knows what Londoners think of it.
So Boris's "game-changing" £3 giveaway is the least appealing of all the major policies proposed so far. Even Brian Paddick's 'early bird' fares policy is ranked higher.
Meanwhile Ken Livingstone's proposal to cut fares (which Boris described as "the last thing that Londoners want or deserve") is ranked as the most appealing.
Asked whether they support or oppose a cut to bus fares, 68% of Londoners give it their backing with just 16% saying they're against it.
It would seem that Tony Arbour's claim that fare rises don't matter because most Londoners don't use public transport was slightly off the mark.
And while Boris's campaign have made much of Ken being untrustworthy, the poll shows that even more people mistrust Boris Johnson to fulfil his promises than Ken Livingstone:
The character questions are also bad for Boris with just 13% believing that he is "in touch with the concerns of ordinary people." A disastrous score.
However, there is one area in the poll where Boris is still massively ahead of Ken and that is "charisma."
In a personality-based contest like the Mayoral election this is incredibly important, and does more to explain Boris's headline lead than anything else.
On policies, Boris has put all of his money on a loser. The only thing that's keeping him in the race is his personality versus Ken's.
If Ken's campaign can turn that around then they can win the election. If they can't then they won't.
