Ads: A state-by-state breakdown of who's spending where

By NBC's Domenico Montanaro

Below is a state-by-state breakdown of who is spending where on television and radio ads in this presidential campaign, beginning the week of March 19th, based on a First Read analysis of data provided by ad-tracking firm SMG Delta.

A few takeaways:

Clearly, and not surprisingly, the campaigns see Florida, Ohio, and Virginia as critical. They are far and away Nos. 1, 2, and 3 on the list.

Despite the huge influx of money from outside groups, only in Virginia are Romney and allies out in front. In Florida and Ohio, the Super PACs are chipping in just enough to be on par with Obama.

The Obama campaign came out with this ad Sept. 3 focusing on Romney's tax plan.

North Carolina is No. 4 on the list, and Team Romney has spent a lot more than Team Obama there. That’s interesting considering the state should be "Lean Romney." Team Romney has had had to spend a lot of money there, which may have been the Obama campaign's goal at the end of the day.

By contrast, the “expand the map” Romney states -- places like Pennsylvania, Wisconsin, and Michigan -- are much further down the list. 

Romney's latest ad - this one running in Wisconsin and focuses on his speech at the Republican National Convention. It's his first ad to run in Wisconsin and hasn't shown up yet in ad-spending data

There’s plenty more in here, like where unions like the SEIU are playing (Florida and Nevada) and where Planned Parenthood is (Virginia in particular, and also Florida and Iowa).

But, of course, that spending pales in comparison to what the Crossroads groups, the Koch-backed Americans for Prosperity, and others, are spending everywhere, especially -- again -- Florida and Virginia.

Ad spending by state:

1. Florida - $117.4 million
2. Ohio - $112.1 million
3. Virginia - $85.7 million
4. North Carolina - $56.5 million
5. Colorado – $54.2 million
6. Iowa - $46.6 million
7. Nevada - $38.2 million
8. New Hampshire – $25.3 million
9. Pennsylvania – $19.3 million
10. Wisconsin - $8.1 million
11. Michigan - $8 million
12. Minnesota - $3.2 million
13. New Mexico - $49,000

Total booked on TV and radio this presidential general election: $575 million
