Presidential Candidate Hillary Clinton Holds Connecticut Campaign Rally

The biggest difference between presumptive Democratic presidential nominee Hillary Clinton and her Republican rival, Donald Trump, isn't just their position on hot-button issues like immigration or taxes, but how much they're spending to get into the White House.

Bloomberg analyzed data from Kantar Media/CMAG, which shows that the presidential hopefuls are taking two very different advertising approaches as the race for the presidency heats up. The data shows that Clinton, on average, spent about $500,000 per day between June 15 and 27, for an estimated $6 million total. Trump, meanwhile, didn't run a single ad during the same time period (not that he needs to—the media gives him enough coverage for free).

The analysis showed that Clinton is focusing her robust ad campaign on Orlando, Denver, and Raleigh, though her campaign ran almost 10,000 spots in more than 24 markets in the 12-day period, according to Bloomberg.

This is in part thanks to Clinton's plentiful coffers—according to the Center for Responsive Politics, Clinton's campaign has raised over $229 million to date while Trump has raised just $63 million.
