Romney wants to lift 'tone' of campaign

Republican presidential challenger Mitt Romney has accused president Barack Obama of running a campaign “of enmity and jealousy and anger” and called on him to lift the tone of political discourse.

In a close and increasingly acrimonious race, Mr Romney went on national television to say he thinks Mr Obama is “running just to hang onto power, and I think he would do anything in his power” to remain in office.
