The points people make about the BBC are interesting and I take note of them. To my mind, the Democrats have been the bigger story up to now and I think we are right to do more about them; though that balance might well be about to change.
An imbalance in the minutes devoted to each side does not denote bias. What I watch for is a contemptuous attitude towards a party's values - or one that suggests that they are self-evident truths! Having said that, the BBC is a British news organisation and part of our appeal (I hope) is that we offer a foreign perspective. Un-American is okay, it seems to me - but not anti-American.
