What we’re seeing in online disclosures and documents:

Party Favors: National Republican Congressional Committee top spender on indirect expenditures ($22,175,402) followed by Democratic Congressional Campaign Committee ($15,166,819) and Democratic Senatorial Campaign Committee ($11,187,080).

GOP Senate Slackers: National Republican Senatorial Committee lags far behind its Democratic counterpart, having spent just $3,292,267 on independent expenditures. National Association of Realtors (which is backing both Republicans and Democrats) has spent more ($3,716,169). Maybe this is why the U.S. Chamber of Commerce, top spender on electioneering communications ($15,804,292), has spent nearly $11.6 million on a dozen Senate races.

Go East! Despite its name, the Western Representation PAC (which for the most part supports candidates west of the Mississippi–Nevada Republican Senate candidate Sharron Angle and Alaska Republican candidate Joe Miller) is supporting Sean Bielat, running against incumbent Rep. Barney Frank in Massachusetts’ Fourth district. That’s not even in the western part of the state! Bielat recently released a poll showing he trailed Frank by ten points.

Mopping up: Insider firm Blank & Rome registers Marine Spill Response Corporation as a client to follow congressional hearings and administration policy on Deepwater Horizon spill. House Energy & Commerce Committee has already requested documents from MSRC related to its relationship with BP; MSRC controlled “bulk of skimmers listed in oil companies’ contingency plans” and was “formed and funded collectively by big oil companies after Alaska’s Valdez spill in 1989 and run by a former BP executive,” according to Reuters.

Bag men: Troubled J Street PAC bundled $20,292 for Sen. Russ Feingold’s campaign.

Got to be a typo: A Johnny Satterwhite discloses spending $100 million–that’s $100,000,000–lobbying NASA on that agency’s work with the Energy Department to “combine the technologies both entities have pertaining to the access and use Of (LIVA) to generate energy.” In Satterwhite’s registration, filed on April 13, 2010, he wrote, “At this time I am requesting that the Unemployment benefits be extended.” Lobbying certainly pays off!

Second highest: Assuming Mr. Satterwhite really did spend $100 million lobbying, the second highest total spent on lobbying disclosed so far for the third quarter of 2010, is $4.15 million by Boeing. We’re eagerly awaiting the U.S. Chamber of Commerce filing, which, if the past is any guide, should be more robust. While some organizations file early, third quarter lobbying reports aren’t due until Oct. 20.
