With the Obama campaign's $6 million ad buy today, the total for ad spending is just a Crossroads buy short of $600 million.
The new grand total is $597.7 million, according to NBC/SMG Delta.
Crossroads is currently making buys and data is expected later on where and how much.
Here's how the total breaks down:
Team Romney: $313.6 million
Team Obama: $284.1 million
And here are the state totals:
Florida: $121 million
Ohio: $116.4 million
Virginia: $89.1 million
North Carolina is clinging to third with $57.7 million, but with no Obama money on this buy, Colorado is creeping up, now at $56.6 million.
Those states are followed by:
Iowa: $48.2 million
Nevada: $38.4 million
New Hampshire: $28 million
Pennsylvania is seeing little activity and is stuck at $19.3 million.
Wisconsin, with the president's and Romney campaign's buys, is now up to $11.8 million. Wisconsin may be seeing a real battle, as the president will campaign their next week. NBC has maintained Wisconsin as a toss-up state, but neither campaign had been advertising there until this week.
