The political advertising section is fascinating. You can see exactly what ads each entity ran, when, and how many impressions they received. Surprising to see the GOP dominate the spending overall!

I could spend hours here.

I find impressive that on a longer period of time, the US still spent 20 times more on political advertising than all of Europe

Edit: It's far from perfect; if you filter by France you get only belgian, german, and spanish advertising.
