Earlier this week, Doctor Who was the subject of an opinion poll conducted by YouGov, one of the UK's main opinion polling agencies, frequently quoted by the media in relation to political polling. The survey (results here), conducted on Monday and Tuesday, quizzed 1974 British adults on whether or not they were interested in the series. The 31% who expressed an interest were then asked various questions about their favourite Doctors, their political opinions and what sort of actor they would like to see cast as the Twelfth Doctor.
David Tennant was the favourite Doctor of the survey, by some considerable margin - 43% of those who expressed an interest in the series choosing him as their favourite, with Tom Baker in second place with 16%. Tennant was also the most popular choice with supporters of the four political parties noted in the survey - Conservatives, Labour, the Liberal Democrats and the UK Independence Party.
On the subject of who should be the Twelfth Doctor, YouGov's own summary article on their website points out that over half of those who said they were interested in the series felt that the next Doctor should be played by a male actor. "British" and "character actor" were also traits which were strongly supported by those surveyed by YouGov.
The poll and its results have been picked up in various places online, with articles relating to it from sites such as Wales Today and the New Statesman.
