The lobbyist figures we give here could stand some minor refinement. The totals might be reduced somewhat if the CRP [ used Obama's rather narrow definition of "lobbyist." Obama makes a point of refusing money from those who are currently registered to lobby at the federal level. The CRP has a broader definition, counting money from anyone working at a lobbying firm, registered or not, state or federal, and their families as well. By CRP's definition Obama himself has taken in $161,927 from lobbyists.

On the other hand, CRP does not count registered lobbyists who work in-house for corporations, industry groups and unions, but classifies them with their industries. Adding those in-house lobbyists to the total could increase the amounts somewhat. But adding donations from in-house lobbyists and subtracting donations from those who don't meet Obama's strict definition would not be likely to change the total by much, and certainly not by enough to justify Obama's claim that McCain and the RNC are "fueled" by such donations.

Also, for what it's worth, the Democratic National Committee has historically been far more reliant on PAC and lobbyist money than the RNC. In 2004, PACs provided about 10 percent of the DNC's total fundraising and only about 1 percent of the RNC's total, according to the CRP. Obama, after he sewed up enough delegates to win the party's nomination, sent word to the DNC to stop accepting PAC and lobbyist donations.
