Two white supremacists have appeared in court in the US charged with plotting to kill more than a hundred black people including Barack Obama.
While their plan was unsophisticated and unlikely to succeed, it has highlighted some of the attitudes that Obama has had to contend with, attitudes he says are dying out.
Asked about his reaction to the case, Obama said: “I think what’s been striking in this campaign is the degree to which these kind of hate groups have been completely marginalised. That’s not who America is, that’s not what our future is. Our future is what’s reflected in this rally here today.”
The election campaign is now in its final week.
In his speeches Obama is returning to his central theme: change. In stressing the need for hope and unity to overcome fear and division he is trying to deflect the more personal attacks waged against him by his rival.
The Democrat campaign also has far more money than the Republican bid to spend on advertising, starting with a 30-minute documentary to be aired nationwide on Wednesday.
