earmarking campaign contributions

As you know, i've been trying to understand whether donations to the NRCC (for example) are somehow earmarked so that the ultimate source/fundraiser (particularly congresscritters) can be identified and rewarded 'appropriately'.

I may have found part of the answer in this May, 03 article from WaPo which describes the accounting for Blinky's Rangers and Pioneers:

Although no individual could legally give more than $1,000, the campaign circulated pledge sheets inviting donors to raise $250,000 from their friends and subordinates, then tracked the results with a computer code so the donor would get credit for all the checks.

A corner of the form included a four-digit number that the campaign used to track the contributions on spreadsheets. "Remember, your Solicitor Tracking Number is your personal tracking number for money that you raise," the form said. "Please place this number on any check that you solicit."

The campaign also tracked contributions by industry, and Democrats have asserted that the system was set up to expedite reward and punishment. Jack Oliver, the campaign's national finance director, said in a deposition during the campaign-finance litigation that the number was used to prevent disputes over who had raised what.

"The Pioneer system itself, the tracking method was effective because people didn't fight over things like they usually did," said Oliver, now the deputy chairman of the Republican National Committee.

I suspect that there is a similar system in place to track funds raised by congressfolk - and i suspect it's secret. I also suspect that it probably shouldn't be secret.

Is it possible that the only way we can learn about such shenanigans as between Suncruz and Ney if we happen to overturn an errant email?

I wonder how we could get our hands on that list. POGO? i'll dash off an email.
