What it doesn't count is the literal billions that have been spent capturing all of the media outlets (from TV networks and stations to newspapers, and throw in large modern media companies like Meta, Twitter/X, etc.). Also, the Republicans have a stranglehold on "political Christianity", where you basically get party sermons from the pulpit every day and twice on Sundays.

The boost from these far outweighs any specific campaign spending, because these organizations have had years to build up their messaging on their targets, that no amount of specific election campaigning can come close to touching.
