Team Bush has little to show for $20 million spent on TV ads

Jeb Bush and his allies have now spent approximately $20 million in TV ads in the 2016 presidential race — more than twice as much as any other candidate or outside group, according to ad-spending data from NBC News partner SMG Delta.

And they have little to show for it, will poll numbers for Bush currently stuck in the single digits both nationally and in the early states.

The pro-Bush Super PAC, Right to Rise, has spent $19.5 million in TV ads in Iowa, New Hampshire and South Carolina, while the campaign has spent an additional $438,000.

By comparison, Conservative Solutions Project — a 501c4 group supporting Marco Rubio that doesn’t have to disclose its donors — has paid $8.4 million in TV ads so far. And Hillary Clinton’s presidential campaign has spent $8.1 million, while the Super PAC backing her has spent an additional $199,000.

Caveat: Because campaigns get discounted ad rates from TV stations, Super PAC and outside groups pay, on average, about four times what a campaign does for the same ad. So money spent is an imperfect way to measure the 2016 TV ad wars, though it gives you a good picture of who is advertising — and by how much.

• Team Bush: $19.9 million ($19.5 million from Right to Rise Super PAC, $438K from campaign)
