This is the latest in a string of attack adverts in the US by a labor-related group called Americans United for Change.  The adverts are trying to cement in the minds of American people that Rush Limbaugh – an ultra-conservative radio talk show host – is the intellectual leader of the Republicans.

This commercial tries to portray the Republican ‘leader’ as trying to do everything he can to make Obama – and therefore America – fail.  Opposition leaders always have a tough time in the early period of a new popular administration and being overly aggressive in your political communication can allow the government to label you a naysayer.
