Hillary Clinton airs 30,700 ads, but Donald Trump stays silent

Meanwhile, anyone flipping through the channels looking for positive ads about Donald Trump would be disappointed: He hasn’t yet put up a spot appealing to November voters, and groups supporting him have been similarly silent.
The lopsided commercial airwaves show the candidates have drastically different views of the importance of traditional political campaigning. Trump says he sees little need for advertising at this stage. Instead, he has been banking on free media coverage propelled by his celebrity appeal.
