Jeb Bush's Big Ad Spending Isn't Helping His Poll Numbers

Jeb Bush's campaign and his Right to Rise Super PAC have spent more than $10 million in TV ads since September -- more than any other candidate or 2016 entity.

Two new polls (Des Moines Register/Bloomberg, Quinnipiac) show him at just 5 percent in Iowa. And another poll (Bloomberg) had him at 10 percent in New Hampshire.

Yet Bush and his Super PAC are outspending everyone else over the airwaves, according to ad-spending numbers from NBC News ad-tracking partner SMG Delta.
