Here's a measure of just how ferocious the Dem assault on the GOP's control of the House has been of late: The NRCC spent an astounding $39.1 million in just the last seven weeks in 59 races across the country, according to a new macro-analysis of spending just released by CQ Politics. Yep, that's more than $5 million per week in the seven-week period analyzed by CQ, which stretched from Sept. 1 through yesterday. And get this: According to CQ's analysis, more than 90 percent of the money -- $36.5 million -- went to 47 districts where the GOP is playing defense. More details on the GOP's flood of cash after the jump.

CQ's analysis found:

* Since Sept. 1, the single district receiving the most such attention from the NRCC, with $2.4 million in expenditures, is Ohio’s 18th District — the seat where the Republicans’ hold has been put at dire risk by the conviction on corruption charges of retiring six-term Republican Rep. Bob Ney.

* The NRCC has also divided $6.2 million almost evenly among three districts in the suburbs of Philadelphia where GOP incumbents face difficult races: the 6th, where two-term Rep. Jim Gerlach is opposed by Democratic lawyer Lois Murphy in a tossup race; the 7th, where 10-term Rep. Curt Weldon is an underdog against Democrat Joe Sestak, a retired Navy vice admiral; and the 8th, where freshman Rep. Michael G. Fitzpatrick is opposed by Democratic lawyer Patrick Murphy, an
Iraq war veteran.

* The House GOP campaign unit also has independently spent $1.8 million since Sept. 1 in Florida’s 22nd District, where 13-term Rep. E. Clay Shaw Jr. and Democratic state Sen. Ron Klein have been raising substantial sums on their own in a contest that is too close to call.

Other districts with top expenditures:

• Iowa’s 1st ($1.57 million): Republican businessman Mike Whalen faces Democratic lawyer Bruce Braley for the seat of eight-term Rep. Jim Nussle, the Republican nominee for governor, in a district that leans Democratic in presidential races.

• Minnesota’s 6th ($1.50 million): Republican state Sen. Michele Bachmann faces Democrat Patty Wetterling, a child safety advocate. Though the district typically leans Republican, Wetterling had a strong candidate debut in 2004 as the challenger to Republican Rep. Mark Kennedy, who left the seat open this year to run for the Senate.

• Connecticut’s 2nd ($1.47 million): Republican Rep. Rob Simmons faces Democrat Joe Courtney, a former state House member, in an eastern Connecticut district that normally has a decided Democratic lean. Courtney is viewed as running a stronger campaign than he did in 2002, when he lost to Simmons by 8 points.

• Indiana’s 9th ($1.42 million): Freshman Republican Rep. Mike Sodrel is opposed by Democratic former Rep. Baron P. Hill, who beat Sodrel as the incumbent in 2002 but was then unseated by him in 2004 by a razor-thin margin.

• New York’s 24th ($1.40 million): GOP Rep. Sherwood Boehlert’s moderate views easily kept this competitive upstate district in his party’s hands over 12 terms, but the seat is up for grabs with Boehlert’s retirement. Republican state Sen. Ray Meier, who is more conservative on some issues than Boehlert, is defending the seat against a vigorous challenge by Democrat Michael Arcuri, a county district attorney.
