As someone once said, information wants to be free. If they're so proud of who they give money to, why do they want to keep it secret? Shouldn't it be a badge of honor to be caught buying politicians:

WASHINGTON — In politics, it is sometimes better to be lucky than good. Republicans and Democrats, and groups sympathetic to each, spend millions on sophisticated technology to gain an advantage.

They do it to exploit vulnerabilities and to make their own information secure. But sometimes, a simple coding mistake can lay bare documents and data that were supposed to be concealed from the prying eyes of the public.

Such an error by the Republican Governors Association recently resulted in the disclosure of exactly the kind of information that political committees given tax-exempt status usually keep secret, namely their corporate donors and the size of their checks. That set off something of an online search war between the association and a Washington watchdog group that spilled other documents, Democratic and Republican, into the open.

The documents, many of which the Republican officials have since removed from their website, showed that many of America’s most prominent companies, from Aetna to Walmart, had poured millions of dollars into the campaigns of Republican governors since 2008. One document listed 17 corporate “members” of the governors association’s secretive 501(c)(4), the Republican Governors Public Policy Committee, which is allowed to shield its supporters from the public.

“This is a classic example of how corporations are trying to use secret money, hidden from the American people, to buy influence, and how the governors association is selling it,” said Fred Wertheimer, the president of Democracy 21, a nonpartisan group that advocates more transparency and controls over political money.

The trove of documents, discovered by watchdogs at the Democrat-aligned Citizens for Responsibility and Ethics in Washington, or CREW, sheds light on the secretive world of 501(c)(4) political groups, just as the battle over their future intensifies. Unlike the Republican Governors Association, the tax-exempt Republican Governors Public Policy Committee is not required to disclose anything, even as donors hit the links, rub shoulders and trade policy talk with governors and their top staff members.

At a policy committee symposium last year at the Omni La Costa Resort and Spa in Carlsbad, Calif., committee members included the health insurers Aetna and WellPoint, the insurance lobby America’s Health Insurance Plans, the utility giant Southern Company, and the lobbying firms Dutko Grayling (now known as Grayling), BGR Group and Leavitt Partners.

With Congress producing so little legislation, governors’ offices have become attractive targets, Mr. Wertheimer said. Last year, the Republican Governors Public Policy Committee allowed corporate donors to make their cases on how to carry out the Affordable Care Act; discuss hydraulic fracturing, an oil- and gas-exploration method regulated at the state level; and hash over state budgets just as coffers began to loosen.

The spokeswoman for the governors association, Gail Gitcho, said the organization did not reveal the names of donors to its tax-exempt arm, and she denounced CREW as a group of partisan hypocrites who refused to divulge their own donors as they unmasked others. CREW has for years maintained that it is nonpartisan, but last month, it was taken over by David Brock, a former conservative who now runs a network of groups aligned with Democrats.
