Reports filed with the Federal Election Commission late Friday show Republicans picking up serious ground on the financial front, but only thanks to Mike Duncan's efforts at the Republican National Committee. As GOP campaign committees in both the House and the Senate continue to lag far behind their Democratic counterparts, RNC fundraising, thanks perhaps to a nomination battle that wrapped up far earlier than the Democrats' did, continues to outpace the Democratic National Committee by leaps and bounds.

The RNC raised $24.3 million in May, FEC reports show, while spending $11.5 million. The DNC raised just $4.8 million and spent $5.2 million. After John McCain clinched the GOP nomination, the party began raising funds through the Victory program, a joint fundraising effort with their presidential nominee. Republicans ended the month with a whopping $53.5 million in the bank, compared with just $3.9 million on hand for the DNC.

Barack Obama's clinching the nomination in early June should boost Democrats' fundraising numbers this month, though the South Capitol Street gang has a long way to go to catch up to their rivals at the Capitol Hill Club.

House Democrats continued to put distance between themselves and the National Republican Congressional Committee in May, raising $6.1 million and spending $4.2 million to end the month with $47.1 million in the bank. Republicans raised $5 million and spent $5.1 million, to finish with $6.65 million on hand. Much of both parties' spending went to early May special elections in Louisiana and Mississippi, both Republican seats which Democrats won.

Perhaps most telling, Democratic members of Congress are investing in their own conference. Last month, members gave $1.9 million to their own cause, building the party's cash-on-hand edge to a more than seven-to-one ratio. Republican members of an NRCC oversight committee, meanwhile, have complained about a lack of contributions from their own members, many of whom have apparently decided to stockpile their own cash in the event they, too, have more competitive races than expected.

On the Senate side, Democrats outraised Republicans as well, though Republicans earned enough to close their own yawning disparity. The Democratic Senatorial Campaign Committee raised $5.9 million and spent $4.9 million, to end the month with $38.5 million on hand. Much of the money went to building field organizations in key battleground states, a process which began last month. The National Republican Senatorial Committee raised $4.9 million and spent $2.7 million, bringing their total in the bank to $21.5 million.

Both Senate committees have something to brag about this month. Republicans point out that they are in better position than they were in 2006, with nearly $3 million more in the bank and having raised more than they did two years ago last month. Democrats, though, have also raised more, and their cash on hand advantage is up slightly from two years ago.
