Why Trump had better start buying TV ads

Throughout his campaign, Donald Trump has prided himself on not needing traditional paid television ads. By May, he had spent $18.5 million on advertising — substantially less than Bernie Sanders, Marco Rubio, Jeb Bush, Hillary Clinton and Ted Cruz, slightly less than John Kasich.

As NPR’s headline writers put it, “Sanders has spent the most on ads, but Trump has spent best.” In lieu of a massive ad budget, Trump instead overwhelmed his foes by amassing nearly $2 billion in free media by mid-March.

The pattern has continued in the general election. By June, Clinton was outspending Trump 15-to-1 on ads. She’s up on the air in swing states and during the Olympics, Trump is not. But he’s still dominating the headlines.
