More and more money is getting thrown into the presidential race. July was the biggest month for both candidates. And Hillary Clinton has a huge overall lead in the spending race, pulling in $52 million over Donald Trump's $36.7 million.
However, Trump's campaign only spent $18.5 million, compared to Clinton's $38 million.
And the candidates are getting their dollars from different places. Let's break it down.
Clinton is pulling in a lot of money from millionaires and billionaires. USA Today reports Clinton pulled in $7 million alone from California environmentalist Tom Steyer's super PAC, for instance.
However, Clinton nearly doubled her donations from smaller donors, pulling in $11. 4 million - good for 36 percent of her total fundraising.
So far, $100 million of Hillary's campaign has gone into TV ads like this one.
Meanwhile, Trump is focusing a lot more on smaller donations. Almost 65 percent of his total income came from people giving $200 or less. That's not a surprise, given his focus on being the "outsider" candidate. But he still pulled in $4.5 million from two super PACs, including a $2 million donation.
And Trump still has money of his own he can use.
Trump's campaign first general election TV ad was released Friday.
But some of Trump's money (about $782,000) is going to Trump-owned companies, like his airline Tag Air. He also spent $8.4 million for advertising from a business that has worked for several other Trump family businesses, USA Today reports.
