With his new battleground-state advertising blitz, Donald Trump has narrowed his ad-spending gap with Hillary Clinton, but still trails by a wide margin.
According to numbers from Advertising Analytics, the Clinton campaign has spent more than $81 million over the airwaves during the general election, while Trump's campaign has spent more than $13 million -- a 6-to-1 margin.
But last week, Clinton's camp was outspending Trump by 10-1, 75 million to $7.7 million.
When outside spending from Super PACs is factored in, Team Clinton is outspending Team Trump, $132 million to $28.7 million.
That 5-to-1 margin is consistent where it was last week.
And in the battleground states for this week alone, Team Clinton is outspending Team Trump, $9.8 million to $6.9 million.
