Don't write off Red Ken just yet. The first YouGov poll  on the London mayoral race puts Boris ahead on first preferences by just two points (46 per cent). There are still other candidates to come, not least from the Greens and the Lib Dems, who could cut into Ken's vote ("Liberal Democrat candidate" is on 4 per cent and "some other candidate" is on 7 per cent), but this poll will reassure Labour officials rattled by an earlier ComRes survey  that put Boris nine points ahead.
The significant support for Ken suggests that his age (he will turn 67 in June 2012) and his political baggage aren't necessarily barriers to his re-election. The poll also found that 56 per cent of voters approve of his time in office and that Ken is seen as more competent (52 per cent to 45 per cent) and in touch (44 per cent to 40 per cent) than Boris.
There is still plenty of ground to make up: in a straight contest between the pair, Boris would beat Ken by 46 per cent to 41 per cent, and 58 per cent of voters approve of his record. But this poll provides the Livingstone campaign with plenty of reasons to be cheerful.
