Fortunately, We've got McCain-Feingold

According to National Journal's Congress Daily (paid subscription required), the Republican Party is asking House members to cough up money for the fall campaigns - they hope to get members to contribute over $17 million.

Majority Leader Boehner donated $550,000 and Majority Whip Blunt contributed
$500,000 at the weekly House Republican Conference meeting. The top four elected GOP leaders are each expected to contribute $550,000 toward the effort. The
program asks members to contribute funds directly to the NRCC from their
campaign re-election accounts or leadership PACs, or in fundraising drives for
the committee. The NRCC has set a fundraising target for each member, depending
on that member's seniority, committee leadership and political vulnerability. An
NRCC spokesman said the targets range from $70,000 for GOP incumbents in
difficult races to $550,000 for elected leaders. Reps. Adam Putnam, R-Fla., John
Shimkus, R-Ill., Todd Tiahrt, R-Kan., and Patrick McHenry, R-N.C., will serve as
deputies to assist Cantor in collecting checks from their Republican colleagues.

In the past, the parties would just raise "soft money" for this type of thing, but then McCain-Feingold prohibited party committees from raising soft money. Now we've got members spending more time than ever raising cash. Now there's improvement.
