Outside groups make up almost half of all presidential campaign ads Outside groups have accounted for almost half of all ad spending during this presidential general election, according to a First Read analysis of data provided by ad-buying firm SMG Delta. Groups supporting the presidential candidates but not affiliated with the campaign, including super PACs, have spent $267 million of the $605.7 million spent on television and radio ads. As NBC's Mark Murray and Domenico Montanaro discuss, both President Obama and Mitt Romney are facing unrest this week - Obama with continued protests in the Middle East and Romney within his own campaign. That overall number is sure to climb, as the Romney campaign is booking buys today. That means about 44 cents of every dollar spent on ads this election has come from outside groups. There's a big difference between who they're supporting. Three-quarters of all money spent by outside groups -- $212 million -- has gone to support Republican presidential nominee Mitt Romney. Two-thirds of all the ads run to support Romney, including the campaign, have come from outside groups. By contrast, 20 percent of ads supporting President Barack Obama's re-election effort have come from outside groups. Team Obama $286,905,268 Team Romney $318,396,978 Team Romney $212,458,408 (67 percent of total) Team Obama $57,473,660 (20 percent of total) Outside groups" spending tracks with the campaigns in some ways with heavy spending in Florida, Ohio, and Virginia. But in states where the campaigns aren't spending heavily, outside groups have stepped in to account for most of the political advertising to test out messages and try to move the needle, so to speak. Florida, like with the campaigns, is seeing the most total spending from outside groups -- $58.6 million. That's just about half of the $121 million total spent in the state. Next up in total spending: Ohio $42.6 million, Virginia $33.3 million, Colorado $25.1 million, North Carolina $21.2 million, Iowa $19 million, Pennsylvania $14.4 million, Nevada $14.2 million, Wisconsin $13.4 million, New Hampshire $11.9 million, Michigan $10 million. By percentage of total spending in that state: Michigan 99.9 percent, Wisconsin 92 percent, Pennsylvania 75 percent, Colorado 44 percent, Wisconsin 42 percent, Iowa 40 percent, Virginia 37 percent, North Carolina 37 percent, Nevada 37 percent, Ohio 36 percent. Strikingly, in every state, outside groups have made up a majority of all ads supporting Romney. In Florida, in particular 73 percent of all ads supporting Romney have come from outside groups. Though the Obama campaign has spent a whopping $46 million in Florida, outside groups have helped Romney even the score. The Crossroads groups have poured in more than $25 million, the Koch-brothers-backed Americans for Prosperity $9 million, Restore Our Future $8 million, America's Future Fund $1.4 million, and the American Energy Alliance $850,000. They have combined with the Romney campaign for $60.3 million in the Sunshine State, about what Obama has spent with the help of outside groups -- $60.7 million. The Obama campaign has gotten some help from outside groups in Florida, but not to the level Romney is benefitting. Priorities USA has spent $12.7 million there, followed by the SEIU $1.5 million, Planned Parenthood $450,000, MoveOn.org $64,000 and the ACLU $17,000. Here's how it breaks down by state (plus a grand total of how much each group has spent below that): Here's the total of how every group is spending: Obama $233,604,018 Crossroads GPS $59,977,352 (pro-Romney) Romney $87,648,202 American Crossroads $48,441,218 (pro-Romney) Americans for Prosperity $46,517,357 (pro-Romney) Priorities USA $48,176,176 (pro-Obama) Restore Our Future $44,408,615 (pro-Romney) Republican National Committee $18,723,265 (pro-Romney) Concerned Women for America $4,783,656 (pro-Romney) America's Future Fund $4,580,908 (pro-Romney) Americans Energy Alliance $3,201,354 (pro-Romney) SEIU $2,497,313 (pro-Obama) Planned Parenthood $1,447,734 (pro-Obama) Priorities/League of Conservation Voters $979,048 (pro-Obama) MoveOn.org $166,891 (pro-Obama) Numbers USA $115,051 (pro-Romney) ACLU $34,088 (pro-Obama) Jill Stein (Green Party presidential candidate) $38,175 TOTAL $605.7 million
