Hillary Clinton Outspends Donald Trump by $20 Million on Television Ads in June Trump's campaign has spent no money on television advertising.

 -- When it comes to television advertising, Hillary Clinton is blowing Donald Trump out of the water.

Clinton and her allies have outspent Trump forces by more than $20 million in June on television advertising, according to an ABC News analysis of CMAG/Kantar Media data.

For every $1 that Trump and his allies spent on television in June, Clinton and her allies spent $12. The presumptive Democratic nominee and her main super PAC, which can raise unlimited funds, doled out about $23 million during the month of June.

Almost 9 in every 10 dollars spent on television in June were spent boosting Clinton’s campaign. Six in 10 dollars came from Priorities USA Action, the Clinton-backing super PAC, with another quarter of spending coming from Clinton’s campaign itself.

Trump’s campaign, meanwhile, has spent no money on television advertising, while unofficial super PACs backing his bid spent less than $2 million.

The lack of advertising spending isn’t a change in strategy for the real estate mogul -- his bare-bones primary campaign relied heavily on dominating news coverage, but spending little money on advertising or staff.

But this means Clinton’s ground game has a monumental head start moving into the general election. Her campaign and her main super PAC have almost $100 million the bank -- more than 20 times as much as Trump and his allies. And according to campaign finance records, Clinton has nearly 10 times as many staff on her campaign’s payroll: 684 vs. 70.

The Sanders campaign and environmentally-focused super PAC NextGen Climate also each spent money leading up to the California primary during the first week of June.
