A whopping 95% of the TV ad spending in the Republican presidential race has come from outside groups and Super PACs, while just 5% comes from the actual campaigns, according to an NBC News analysis of TV ad spending data from SMG Delta.
The opposite is true on the Democratic side — 95% of the TV ad spending in the Democratic presidential contest has come from the campaigns, versus just 5% from outside groups.
Another way to look at the TV ad spending to date: In the GOP race, outside groups (about $42 million) are outspending the campaigns ($2 million) by more than a 20-to-1 ratio. And in the Democratic primary contest, the campaigns ($7.5 million) are outspending the outside groups (about $400,000).

(Note: This analysis doesn’t include outside spending from groups unaffiliated with 2016 candidates, like the conservative Club for Growth, which has spent nearly $1 million against Donald Trump in Iowa.)
Cases in point: Right to Rise, the Super PAC benefitting Jeb Bush, has spent $15.5 million in TV ads so far. But the Bush campaign itself has spent less than $440,000.
Additionally, the 501c4 outside group Conservative Solutions Project — which, unlike Super PACs, doesn’t have to disclose its donors — has spent nearly $7 million to help Marco Rubio. But the Rubio campaign itself hasn’t spent a single cent on the TV airwaves.
