Republican presidential candidate Mitt Romney waves as he takes the stage for a campaign event at a window and door factory, Thursday, Nov. 1, 2012, in Roanoke, Va.

An unprecedented $143 million has been spent this week, far-and-away a record for this presidential cycle -- with more ads already being booked today. 

Team Romney, including the campaign and groups supporting the Republican challenger, are outspending Team Obama $96.4 million to $46.2 million this week. Accounting for this massive spending disparity, there are 11 outside groups pitching in to support Romney this week while just two are doing the same for Obama.

But despite the massive spending advantage Team Romney is enjoying over Team Obama, they are about even in ad points, according to SMG Delta. In other words, they are running about the same number of ads.  

MSNBC Contributor Robert Traynham, The Associated Press' Liz Sidoti, The National Review's Jim Geraghty and former senior advisor for Vice President Al Gore, Michael Feldman, join The Daily Rundown's Chuck Todd to discuss how close the race can be.

That's because the Obama campaign booked advertising well in advance, as compared to the Romney campaign which makes buys days -- sometimes the day -- before. Outside groups also have to pay more than campaigns for their ads.

Overall, Team Romney has outspent Team Obama $573.2 million to $394.4 million in this election.

The vast majority of outside money has gone to support Romney. In fact, 85 percent of all outside money poured in during this campaign has gone to support Romney or oppose Obama. 

Nearly two-thirds -- 63 percent -- of all the money going to support Romney has come from outside groups. By contrast, just 16 percent of the money supporting the president has come from outside groups.

Outside money
Pro-Romney: $363 million
Pro-Obama: $63.5 million
Total: $426.5 million
