Hillary Clinton and her allies continue to outspend Donald Trump and his backers over the airwaves by a 15-to-1 margin, according to ad-spending data from SMG Delta.
Team Clinton has spent $57 million on ads so far in the general election -- $25 million coming from the campaign and another $32 million from pro-Clinton Super PACs.
By comparison, Team Trump has aired $3.6 million in ads, with all of the spending from two outside groups, the National Rifle Association ($2.3 million) and Rebuilding America Now ($1.3 million). The Trump campaign has yet to spend a single cent on ads so far in the general election.

Clinton's advantage is even more pronounced in the battlegrounds, where Team Clinton has spent a combined $46.2 million in nine states to Team Trump's $1.2 million. That's nearly a 40-to-1 margin.
