Two things we find almost every time. First, the “paid for by” disclaimer is under the FEC minimum for internet video — at least four seconds on screen and letters at least four percent of picture height — or it’s missing from the streaming cut, and the per-state disclosure and recordkeeping rules for the targeted states were never mapped. Second, the buy is targeted to a DMA that bleeds across district and state lines, so a congressional-district race pays for impressions outside the district — and no in-district geo holdout was reserved, so incrementality cannot be proven before the polls close.
