Ad spending on television and radio in the presidential election may hit $1 billion by November 6, according to an analysis by NBC News. With 20 days to go, spending has already hit $807 million.
The Obama campaign is one ad buy away from reaching $300 million by itself. But with outside money factored in, “Team Romney” (the campaign plus outside groups supporting him or attacking the president) is outspending “Team Obama” $455 million to $352 million.
The Romney campaign, which has come on since Labor Day, is now the second-biggest spender at $164 million.
NBC has more details on the top spending groups.
