Democrats are outspending Republicans on political ads by about a half-billion dollars since Aug. 1, according to data from analytics platform AdImpact.
By the numbers: As of Sept. 20, Democrats have spent $1.8 billion on ads booked for Aug. 1 through Nov. 5, compared to $1.3 billion for Republicans.
- That includes spending by campaigns (from the presidential candidates down to lower-ballot hopefuls) as well as by outside groups.
- Campaigns alone, Democrats have spent nearly $700 million, compared to almost $400 million by Republicans.
Zoom in: Both parties are spending the most on ads running in Philadelphia, Detroit and Phoenix, among the metro areas tracked by AdImpact.
What's next: With about a month and a half until Election Day, there's no end in sight for campaign ads — especially if you live in a swing state.
